However, it requires lengthy observations. But my guest, Dr Geraint Lewis, has a hack up his sleeve — gravitational lensing. 👉 Redshift Drift story on Universe Today: https://www.universetoday.com/162845/a-new-way-to-measure-the-expansion-rate-of-the-universe-redshift-drift/ 👉 The Redshift Difference in Gravitational Lensed Systems: A Novel Probe of Cosmology: https://arxiv.org/abs/2308.07529 👉 Dr Geraint Lewis' website: https://www.geraintflewis.com/ 👉 Twitter/X: https://twitter.com/Cosmic_Horizons 🦄 Support us on Patreon: https://patreon.com/universetoday 📚 Suggest books in the book club: https://www.goodreads.com/group/show/1198440-universe-today-book-club 00:00:00 Intro 00:01:41 Understanding the expansion of the Universe 00:03:10 Hubble Tension and Crisis in Cosmology 00:05:53 Cosmic ladder of distances 00:17:30 CMB measurements 00:24:47 The Boring Solution 00:31:10 The Exciting Solution 00:37:25 Red Shift Drift 00:48:05 Time machine for free 00:54:14 Perfect solution with unlimited funds 00:57:05 Advice for young astronomers 01:03:44 Outro 📺 VIDEO VERSION https://youtu.be/JGYHwpsMQ1w 📰 EMAIL NEWSLETTER Read by 60,000 people every Friday.

In this week's questions and answers show, I explain how JWST and other telescopes see color, how images from observatories are released to the public, and how much of the sky can JWST see. Also, a bunch of non-Webb questions too. 00:00 Start 01:55 [Tatooine] How does JWST see color? 09:58 [Coruscant] How are astronomical images released to the public? 12:52 [Hoth] How does JWST handle spacedust? 14:48 [Naboo] How is JWST pointed? 16:39 [Kamino] Could dark matter be detected in specific parts of the Universe? 18:52 [Bespin] Is dark matter just a smart guess? 23:10 [Mustafar] Why does Earth have water and the Moon doesn't? 26:09 [Alderaan] Is Panspermia inevitable? 28:28 [Dagobah] Is the Big Bang a past event or is it still happening? 29:43 [Yavin] What's the best telescope to see planets? 31:19 [Mandalore] If we mapped the CMB from Andromeda, would it look different? 33:10 [Geonosis] Why do we see light from long ago, shouldn't it have passed us? 34:49 [Corellia] How can we promote diversity in STEM? Want to be part of the questions show? Ask a short question on any video on my channel.

Dr. Paul Hickson is a professor of astronomy and astrophysics at the University of British Columbia. Dr. Hickson is overseeing a team that built a telescope out of liquid mercury in India. The International Liquid Mirror Telescope is 4 meters across and built on top of a 3,000-meter mountain in India. This will prove the technology and allow for larger and larger liquid mirror telescopes on Earth (and eventually in space). https://science.ubc.ca/news/indian-ubc-astronomers-celebrate-first-light-liquid-mirror-telescope 🚀 OUR WEBSITE: ════════════════════════════════════ https://www.universetoday.com/ 🚀 PODCAST LINKS: ════════════════════════════════════ RSS: https://universetoday.com/audio iTunes: https://universetoday.com/itunes Spotify: https://universetoday.com/spotify 🚀 EMAIL NEWSLETTER: ════════════════════════════════════ Read by 50,000 people every Friday.

Einstein's Theory of General Relativity has been tried and tested many times, and so far, Einstein was right. But we know his theory must be incomplete, as it still doesn't integrate with quantum mechanics. Where are physicists searching next for the future of cosmology and relativity?

How did life go from single-celled to multi-celled? Dr. William Ratcliff is an Associate Professor and Co-Director of the Interdisciplinary Ph.D. in Quantitative Biosciences at the School of Biological Science at Georgia Tech. Dr. Ratcliff and his collaborators are working with single cells of yeast, watching them make the jump to become multi-cellular organisms. It turns out, life has done this many times in the past, and not just the jump that created the modern animals we know of today. https://biosciences.gatech.edu/people/will-ratcliff 🚀 OUR WEBSITE: ════════════════════════════════════ https://www.universetoday.com/ 🚀 PODCAST LINKS: ════════════════════════════════════ RSS: https://universetoday.com/audio iTunes: https://universetoday.com/itunes Spotify: https://universetoday.com/spotify 🚀 EMAIL NEWSLETTER: ════════════════════════════════════ Read by 50,000 people every Friday.

My guest today is Dr. Nikku Madhusudhan, a PhD astronomer at the University of Cambridge. Dr. Madhusudhan is one of the researchers who investigated the habitability of "hycean worlds"; ocean worlds with a thick hydrogen ocean. These worlds are completely alien to anything we have in the Solar System, and yet, could have a much wider region that remains habitable than terrestrial planets. https://people.ast.cam.ac.uk/~nmadhu/Nikku_Madhusudhan/Home.html 🚀 OUR WEBSITE: ════════════════════════════════════ https://www.universetoday.com/ 🚀 PODCAST LINKS: ════════════════════════════════════ RSS: https://universetoday.com/audio iTunes: https://universetoday.com/itunes Spotify: https://universetoday.com/spotify 🚀 EMAIL NEWSLETTER: ════════════════════════════════════ Read by 50,000 people every Friday.

10 billion years ago, galaxies of the Universe were ablaze with the light of newly forming stars. This epic phase of history is known as “Cosmic Noon” - the height of all star creation. Galaxies like our Milky Way aren’t creating stars at nearly the rates they were in the ancient past. However, there is a time when galaxies in the present can explode with star formation – when they collide with each other. This recently published collage of merging galaxies by the Hubble HiPEEC survey (Hubble imaging Probe of Extreme Environments and Clusters) highlights six of these collisions which help us understand star formation in the early Universe.

Black holes are already mind-bending enough. Matter and energy compressed into a region so dense that the escape velocity exceeds the speed of light. Places where space and time are tangled up so much that even if you could go faster than light speed, you’d still end up at the singularity. Astronomers know of two kinds of black holes in the Universe: stellar mass and supermassive, and how we get them have been worked out pretty well. But there’s a third class of black hole, one which has never been observed nor detected indirectly, and yet it could explain some of the mysteries of the Universe, including the nature of dark matter. Primordial black holes.

Well, did you hear the big news? Life on Venus. Life… on... Venus. Now, where have we heard this before? Oh right, life on Mars. If you’ve been watching any of my videos or listening to Astronomy Cast, you’re cautiously optimistic. Skeptical, but hopeful. That’s the right position to take, because buckle up, the internet’s about to run with this news. It’s going to be difficult to figure out what was really discovered, and what this means for the search for life in the Universe. Want to see this video early?

When the Apollo astronauts first landed on the Moon, they couldn’t go far on foot. That’s why the three final missions were equipped with Lunar Roving Vehicles, or Moon buggies, which allowed the astronauts to cover much more ground and do more science. Now that NASA is returning to the Moon by 2024 as part of its Artemis Program, it’s considering a fleet of new vehicles that will help astronauts roam far and wide across the surface of the Moon. 60 fps Apollo Videos from Dutchsteammachine https://www.youtube.com/channel/UCRGEIYuo_HbUR6GhFLeEkPA Want to see this video early?

When the largest stars die, it’s usually pretty obvious. Supernovae are visible from billions of light-years away. But recently astronomers watched a massive star just disappear. No explosion, nothing, it just… vanished? Of course, it could have been dust. It’s always dust. But one intriguing possibility is that the star just imploded directly into a black hole, without the supernova detonation. And if that’s the case, is this happening more often, we just didn’t notice it? Want to see this video early?

This episode is a segment that we did in the Weekly Space Hangout talking about how astronomers are using masers (water lasers) to measure the expansion rate of the Universe. You'd think that another, independent way to measure the expansion rate of the Universe would be helpful, but it's only deepened the mystery of the cosmological crisis.

Earlier this year, NASA announced 4 new Discovery-class missions that they were considering. These are low-cost, rapidly-built missions that will help scientists understand some mystery in astronomy and planetary science. One of these missions is called Trident, and it’s going to be targeting the Planet Neptune. And more specifically, it’s going to be providing close up pictures of its largest moon Triton.

Astronomers have discovered thousands of exoplanets, and still need to confirm thousands more. And over the coming decades, we’ll probably learn of millions of planets, orbiting stars we’ve never heard of. That’s why it’s reassuring to know astronomers are learning a tremendous amount about the closest star system to our own, Proxima Centauri. In fact, we now know of two planets orbiting the red dwarf star, one of which is in the habitable zone. Thumbnail credit: NASA/Harvard-Smithsonian Center for Astrophysics/D.

I’d say half the astronomy-related videos on YouTube are all about black holes. Clearly, they’re a fascinating topic, but they’re also a mystery. How do you observe something that can absorb all the radiation and matter falling onto them, and nothing can ever escape? How do we know they’re really there, and what are the best observations we can make? Today I’m joined by Dr. Paul Sutter, a cosmologist, and astrophysicist to talk about how we know black holes are really there and not just a figment of an astrophysicist’s imagination?

On Sunday, May 31st, 2020, a SpaceX Crew Dragon capsule carrying astronauts Robert Behnken and Douglas Hurley docked with the International Space Station. This was a tremendous accomplishment for SpaceX and NASA, giving the United States the capability of launching its own astronauts, and no longer relying on its Russian partners. This was the 5th time that US astronauts went into orbit on a new kind of space vehicle, following in the footsteps of Mercury, Gemini, Apollo, and the Space Shuttle.

When you’re out in space, water is the most precious resource you can get your hands on. It can be used for air, water, to grow food, radiation shielding, and most importantly, as the propellant for your spacecraft. Exploration of the Moon has revealed that there’s a tremendous amount of water ice locked into the regolith, but it’s probably very difficult to access. But there are also permanently shadowed craters at the Moon’s poles that could have more than enough water to support a permanently inhabitable station on the Moon. But it’s going to be tricky to get at, considering the fact that temperatures in the shadows plunge to -240 degrees Celsius, just 30 degrees above absolute zero.

The distances to other stars are depressingly enormous. Sure, it’s incredibly far to get to Mars, Jupiter, and even Pluto, but at least you can design a robotic spacecraft to make the journey and see the science results in your own lifetime. But in the case of other stars, interstellar flight times will take thousands and even tens of thousands of years to send just a robotic mission. Fortunately, the Milky Way has got our back. Other star systems have been hurling comets and asteroids towards the Solar System. All we’ve got to do… is catch them.

The Moon orbits around the Earth. The Earth orbits around the Sun. And out in the distant Universe, astronomers have found a system that takes this logical progression to its most extreme. There’s a system where a supermassive black hole with millions of times the mass of the Sun orbits another black hole with billions of times the mass of the Sun. How astronomers discovered this incredible interaction took careful observations, imagination, and the hard work of the Spitzer Space Telescope, taken during its final years of operation.

One of the longstanding questions astronomers have had is, are we normal? Is our Solar System a template for what we might expect to see as we look out into the Milky Way at other star systems? As the data continues to come in, the answer to that question really seems to be no, we’re not normal. Star systems seem to have a huge variety of planets orbiting them. Familiar planets like our own terrestrial, gas and ice worlds. But then there are also super earths, mini-neptunes, hot jupiters. And it looks like there are planets, located in their star’s habitable zone, which are completely covered with liquid water. Like, oceans which are dozens and maybe even hundreds of kilometers deep. What would it be like on one of these worlds, and of course, we always want to know, could they be habitable?

Mars has been the destination for so many of our spacecraft, and for good reason, it’s probably the most Earthlike place in the Solar System, with water ice on its surface and reservoirs of the liquid beneath the surface. If we’re going to find life, Mars might be the place. But the tiny moons orbiting Mars, Phobos and Deimos, are scientifically fascinating on their own, and so far, a mission has never reached them. Last week, Japan announced that they’ve greenlit their Martian Moon eXploration mission, or MMX, which will launch an orbiter, lander and maybe even a rover to Phobos in 2024, returning samples back to Earth by the end of the decade.

After almost 50 years since the Apollo Moon landing missions ended, NASA announced that they’re going to return to the surface of the Moon with their Artemis mission, ideally taking the first lunar footsteps in 2024. NASA Administrator Jim Bridenstine asked for additional funding to achieve this goal, and the other branches of government haven’t been as enthusiastic about this plan. So don’t be surprised if the landing date slips to 2028 or even farther. But NASA is moving forward on its architecture to return humans to the Moon, from its launch rocket to the entire method of getting astronauts down to the surface.

Near the end of 2019, astronomers watching the red giant Betelgeuse noted how much the star had dimmed, continuing to steadily fade for months. It’s a variable star, and it’s known to get dimmer and brighter, but the big surprise is that it’s still continuing to dim, recently passing magnitude 1.56 and still getting dimmer. This is unprecedented in the decades that astronomers have been watching the star. The world’s biggest telescopes are on the case, and the European Southern Observatory released dramatic new images of Betelguese, resolving features on the star’s surface and surrounding area showing how it’s dramatically changed over the course of 2019.

It’s hard to really wrap your mind around the vast distances between stars. The fastest spacecraft ever launched into an interstellar trajectory right now is Voyager 1. If it was directed at the nearest star, it would take tens of thousands of years to make the journey across the interstellar gulf. Even so, groups like Breakthrough Starshot and Icarus Interstellar are working on plans right now to try and send spacecraft to other stars, ideally within our lifetimes. But we can see how quickly technology is advancing all around us, from materials science to high energy physics, not to mention reusable rockets. It seems reasonable to ask, should we invest in an interstellar mission now, or wait a few decades or even centuries for better technology to come along which could make the trip much shorter?

On February 9, 2020, the European Space Agency’s Solar Orbiter spacecraft launched from Cape Canaveral Florida on top of an Atlas V 411 spacecraft. The spacecraft’s mission is to fly inside the orbit of Mercury, on a tilted orbit that takes it above and below the Sun, capturing images of the Sun’s poles for the first time. This is just a year and a half after the launch of NASA’s Parker Solar Probe, which will fly even closer. Together, the two spacecraft will measure the Sun from every angle up close, providing detailed images and insights of our closest star, to help understand how it creates and controls the giant bubble of plasma that surrounds the entire Solar System.

You’re looking at the highest resolution image that has ever been taken of our Sun, using the brand new Daniel K Inouye Solar Telescope in Maui. These lighter regions are convection cells, blobs of hot gas the size of Texas which have carried heat from deep below the surface of the Sun, releasing it into space. The darker lines are cooler regions, where the material is sinking back down into Sun. This image is just a demonstration of the incredible power of this 4-meter observatory, which will join NASA’s Parker Solar Probe and ESA’s Solar Orbiter in ushering in the golden age of solar astronomy.

On Sunday, January 19th, 2020, SpaceX launched a Falcon 9 rocket carrying its newly designed Crew Dragon spacecraft. 84 seconds into flight, at the moment of maximum aerodynamic pressure, the capsule fired its eight SuperDraco thrusters, detaching from the top of the rocket and flying ahead. Moments after, the Falcon 9 rocket exploded in midair, destroying a completely good rocket, but the capsule was completely safe, jettisoning its trunk and landing gently in the ocean a few minutes later. Nobody was on board the spacecraft, just a couple of test dummies, but this test proved that in the case of an emergency during the ascent stage fo the mission, Crew Dragon would be able to carry its astronaut crew to safety.

In 2006, astronomers spotted the telltale sign of a supernova detonating in the galaxy NGC 1260, located about 240 million light-years away in the constellation of Perseus. As telescopes around the world turned their collective light-gathering power on the expanding explosion designated as SN 2006gy, they realized they were seeing something very unusual. This clearly wasn’t a regular supernova. It grew to be 100 times brighter than the typical stellar explosion and lasted much much longer. More than a decade after that cosmic explosion, astronomers finally think they know what series of events led to the release of this much energy, now called a superluminous supernova. A red giant ate a white dwarf. An event so rare it probably accounts for only 1 in 1000 supernovae.

Whenever I talk about the search for life in the Universe and its emphasis on water, I get comments that scientists aren’t being creative enough. Why does life rely on water? Couldn’t there be lifeforms which are completely different from life on Earth? Isn’t that the textbook definition of alien? Astrobiologists have only scratched the surface in their search for life in the Universe, and they’re going after the low-hanging fruit. Since life on Earth can be found wherever there’s water, why not check out the water on other worlds? If that doesn’t pan out, then they’ll expand the search. But it’s possible there are aliens living right here on Earth among us, in a shadow biosphere, we just haven’t detected them yet.

In 2015, scientists discovered the telltale signal from ripples of spacetime sweeping over the Earth. It was the very first direct detection of gravitational waves, generated by the merger of two massive black holes 1.3 billion light-years away. This discovery was the culmination of decades of research and construction of huge instruments called interferometers to detect the warping of spacetime caused by gravitational waves. Today, the most advanced detectors, the LIGO/VIRGO collaboration, have turned up over 50 gravitational wave discoveries - on average one every week - allowing astronomers to perceive the Universe in a completely different way. What new gravitational wave instruments are in the works, and what does the future hold for this relatively new field of study?

We’ve now passed the 50th anniversary of the Apollo 11 landing, and all eyes are back on the Moon. NASA is planning to return to the Moon by 2024 with its Artemis mission, the Chinese have put the Moon firmly in their plans for space exploration, and even SpaceX thinks the Moon is the perfect destination to test out the capabilities of its Starship. But what can you do with the Moon? Refuel spacecraft with resources drawn from the lunar regolith? Mine its helium 3 for your fusion reactors? Build a lunar amusement park? In fact, the far side of the Moon might make one of the best platforms we have for radio telescopes. One side of the Moon is completely blocked from Earth’s constantly increasing radio traffic, giving it the perfect view to the most sensitive radio signals in the Universe.

On Monday, January 6th, 2020, another SpaceX Falcon 9 blasted off from Cape Canaveral, carrying another 60 Starlink internet communications satellites, bringing the full size of the constellation to 180. With just three launches, SpaceX becomes the largest satellite operator in the world. But the company is just getting started. They’re planning to do this again every couple of weeks during 2020, bringing the total number of satellites in the constellation to about 1440, which is enough to provide high-speed internet services to the United States and parts of Canada. Shortly after launch, as the satellites are raising their altitude, they’re clearly visible to the eye as they streak across the sky in a close train. Astronomers aren’t happy.

Over the last weekend, astronomy Twitter started noting that the red giant Betelgeuse, the prominent shoulder of Orion was looking visibly dimmer in the sky, and I had a few people reach out to me and ask me if it was really happening and if I knew what was going on. This is exciting, of course, because Betelgeuse is living on borrowed time, and it could explode as a supernova any day now. Or, it might not detonate for another 100,000 years. We just don’t know. What’s Betelgeuse up to? Is this a sign that it’s about to explode? And what would it mean if it did?

As I’m recording this video near the end of 2019, the total number of confirmed exoplanets stands at 4,104. We’ve come a long way since the discovery of the first exoplanet orbiting a sunlike star back in 1995 with 51 Pegasi b. And the reality is that the race to find new exoplanets is only accelerating. New ground and space-based telescopes are turning up planetary candidates at an increasing rate. New techniques will find planets in entirely new ways. The bottom line is that over the next few decades, this mere 4000ish will multiply by orders of magnitude. So let’s run the clock forward and try to calculate what the future holds for exoplanets. How many worlds will we know about 3 decades from now, in the year 2050?

How old is the Universe? In order to figure that out, all you have to do is figure out how quickly it’s expanding, and then the clock backward until everything is crunched together. And astronomers have measured the rate that the Universe is expanding with tremendous precision at various times in its history; at the beginning, and much more recently. The problem is, these expansion rates disagree, but they’ve both been measured so accurately that their error bars don’t overlap. In other words, there are multiple, highly accurate estimates for the age of the Universe, and they disagree.

Extending humanity to other worlds in the Solar System is at the very limits of our modern technology. And unless there are dramatic discoveries in new propulsion systems or we learn how to build everything out of carbon nanotubes, the future of space exploration is going to require living off the land. The technique is known as In-Situ Resource Utilization or ISRU, and it means supplying as much of your mission from local resources as possible. And many of our future exploration destinations, like Mars, have a lot to work with. Let’s look at the raw materials on Mars that missions can use to live off the land and the techniques and technologies that will need to be developed to make this possible.

The exploration of Venus has been mainly about getting down to the surface of the planet. The Soviet Union sacrificed lander after lander to discover just how extreme the conditions are down there on the ground. But higher up, among the clouds, the climate on Venus is surprisingly Earthlike in temperature and pressure, and there have been some fascinating ideas for robotic and human explorers to fly the skies of Venus, to help understand our evil twin planet. Let’s take a look at them.

And a lengthy answer to one of the most common James Webb questions we get: can it be refueled? This was answered by Paul Geithner, a Deputy Project Manager for James Webb during a recent livestream. 01:00 Why do we see meteor showers every year? 02:49 Why not also use 3D printing for space telescopes? 04:40 Why don't they design telescopes for Starship? 07:20 Could there be a privately backed telescope? 09:54 Is there glass on the Moon to build telescopes? 11:46 Could ISS help build new space telescopes? 13:47 Space telescopes on the far side of the Moon? 15:06 Is Andromeda actually much closer? 16:27 Why spend money on science? 19:20 Why is the dark side of the Moon illuminated? 21:34 Can James Webb be refueled?

Today I was joined by Dr. Casey Handmer, an accomplished theoretical physicist who currently works at NASA's Jet Propulsion Lab. Casey has a fascinating blog where he considers current trends in space exploration and what the future holds. Learn more about Casey here: https://caseyhandmer.wordpress.com/ We talked about the implications of SpaceX Starship, Starlink, why power beamed from space or asteroid mining will never turn a profit down here on Earth, and why he's not that scared about space radiation.

When it comes to telescopes, bigger is better. That’s true down here on Earth, and it’s especially true out in space. As astronomers and engineers design the next generation of giant space telescopes, they’re running up against the limits of current launch providers. There are only so many ways you can fold a huge telescope to get it to fit inside a 5-meter launch fairing. The upcoming James Webb Space Telescope is pretty much the very limit of what you can construct on Earth and put into space in a single launch. To go bigger, space agencies will need to consider assembling their next-generation space telescopes… in space.

In this week's questions show, I tackle all the questions about James Webb generated by the videos we did this week. Can it be refueled? How can it see the entire sky? Is the delay a blessing? And more... 00:30 How will JWST run out of propellant? 03:12 Are there spacecraft that could service JWST? 05:00 Can JWST only see half the sky? 08:21 Is the delay a blessing in disguise? 10:58 Why not construct it in Low Earth Orbit? 13:09 Could we build a copy? 14:29 Could JWST use gravitational lensing? 15:55 Will JWST image black holes? 17:52 Is the telescope an antique? 18:49 Should we look or explore? 20:52 Could it find vegetation? 22:00 Is James Webb already a failure?

Today I'll be joined by Paul Geithner, the Deputy Project Manager for NASA's James Webb Space Telescope. You've had questions about this mission. Well... now's your chance to get them answered directly from the source. Paul started working with NASA in 1991 on the Hubble Space Telescope, shifting over to James Webb. In 2011, he became the Deputy Project Manager, Technical for James Webb.

On March 30, 2021, NASA’s James Webb Space Telescope will blast off from the European Space Agency’s European spaceport in Kourou, French Giana on board an Ariane 5 rocket. It’ll fly to the Sun-Earth L2 Lagrange point, a relatively stable spot in space that keeps the glare from the Sun, Earth, and Moon all in a tiny spot in the sky. Then, it’ll unfurl its tennis court-sized sunshade, fold out its gigantic 6.5-meter mirror, and peer out into the distant cosmos. Over the course of the next 10 years, this infrared observatory will help astronomers learn about the earliest moments of the Universe, directly observe the atmospheres of planets orbiting other stars, and peer at newly forming stars and planets. And if you listened to the words I just said with equal parts terror and skepticism, I don’t blame you. James Webb’s path to space has been long and tortuous. And the risks that the mission still faces are very real. Hopefully, the science will be worth it. Hopefully, nothing else goes wrong from now until deployment. So today, I want to do a deep dive into James Webb. To talk about the history of the mission, why it exists, how the development went, and where it stands today. I’ll warn you though, the length of this video is going to go way over budget.

It was another solo live QA this week and I did my best to answer as many audience questions as I could do, closing in on 60 questions during the hour. Needless to say it was a wide-ranging conversation with questions about where I think rovers should go, what do I think about time travel, and whether we should do more SETI or build more space telescopes.

Solar energy is the ideal way to power a spacecraft. There’s no weather, there’s no pesky atmosphere, just pure photons streaming from the Sun to harvest for whatever you need. Well, as long as you’re within the inner Solar System. But solar panels are complicated and fragile made of sensitive electronics and glass - not to mention, really heavy. Any spacecraft equipped with solar panels needs to handle the gravity down here on Earth for the construction and testing, then the shaking and high Gs of launch. The solar panels need to unfold perfectly once they get to space. And the total amount of energy you can harvest is limited by the size of your rocket’s launch fairing. Maybe there’s a new strategy. NASA is currently funding research into a new type of solar panel that can be carried into space as a liquid and then sprayed onto a surface to turn it into a power generating surface.

The race is on to find life in other places in the Solar System, from underground reservoirs on Mars to the subsurface oceans on Europa and Enceladus. If spacecraft, rovers or even astronauts make the momentous discovery of life on another world, that’ll just open up new questions. Did it originate all on its own, completely independently from Earth, or are we somehow related? And if we are related, how long ago did our evolutionary trees branch away from each other. Even though Mars is millions of kilometers away, it could be possible that we’re still related thanks to the concept of Panspermia; the idea that meteor impacts could transfer rocks and maybe even living creatures from world to world. But could you go one step further? If we find life on another star system, could we discover that we’re actually related to them too? Is Galactic Panspermia possible?

If you’ve watched this channel enough, you might have the impression that I hate Venus. It’s possible, just possible I’ve even suggested that the planet is so terrible it should be pushed into the Sun. The reality, of course, is that it’s an absolutely fascinating world - the closest twin to the Earth that we have in the Solar System. It’s nearly the same mass and has the same surface gravity. While Earth is the beautiful life-filled world we all enjoy, Venus is a tortured hellscape, with temperatures hot enough to melt zinc. With atmospheric pressures more than 93 times what we experience here on the surface of Earth. And I always forget about the sulphuric acid rain. The Soviets sent a series of landers to a horrible demise for a glimpse of the surface of Venus in the 70s and 80s. But nobody’s been back since. There have been new techniques and technologies in development that might make a serious exploration of the surface of Venus possible again. Exploration that could help us understand why the planet went so horribly horribly wrong.

Scientists have had the opportunity to examine several asteroids in the Solar System now, and what they’ve learned is how much variety is out there, depending on the mass, distance from the Sun and composition. Astronomers currently know of 829,400 asteroids across the Solar System, and they’d love to visit as many of them as possible to learn more about them. Considering the price of a single spacecraft, that’s going to get expensive. Fortunately, there are places in the Solar System that have trapped a large number of asteroids in a way that a single spacecraft can visit several of them as part of a mission. They’re at Jupiter’s L4 and L5 Lagrange points, and this week NASA approved a new mission that’ll explore 7 different asteroids over a 12-year journey. It’s called Lucy.

People always ask me how I think humanity will react if we discover life somewhere out there in the Universe, whether it’s bacteria under the surface of Mars, a biosignature of alien life in the atmosphere of another world, or a radio signal from another civilization. Will our civilization lose its collective mind and have a temper tantrum on a global scale? Will we become one of those purge planets from Rick and Morty? Will the discovery suddenly end all religion, as we wait for guidance from our new alien overlords? Will we gather together as a species to present a common front to whatever cosmic horrors await us beyond the Solar System? In my opinion, if I could sum up the collective response in a single word, it would be: meh.

Even as the first rockets were launched into space decades ago, aerospace knew it was a wasteful process. Rocket stages, motors, and complex equipment crashed into the ocean or burned up in the Earth’s atmosphere. Could spaceplanes bring the costs down? Flying to orbit with a combination of jet engines and rockets and then safely re-enter the Earth’s atmosphere again. Single-stage to orbit spacecraft and spaceplanes have always seemed out of reach, and actually not that practical. But what about a two-stage, fully reusable spaceplane? Exodus Space Corporation has been secretly working on this concept for a decade now, and what they’re proposing is pretty revolutionary.

While we’re all waiting for James Webb to launch - which it will - the Extremely Large Telescope to be constructed, and LUVOIR to get approved. (Please get approved, please get approved.) We’re going to need a way to pass the time. So let’s have our imaginations take flight, out into the Universe, and consider some of the most incredible ideas suggested for telescopes. Unless you’ve been crawling through scientific journals like me, I guarantee you’ve never heard of any of them. But when I’m done, you’re going to want to fund all of them.

After decades of research, including multiple landers and orbiters, science can definitively say: Venus sucks. Seriously, that place is the worst, with its boiling temperature, intense pressure, sulfuric acid rain, and more. But was it always this bad? According to new research from NASA and various universities in Sweden and the US, Venus might have actually been the first habitable world in the Solar System. And it might have maintained a reasonable climate for billions of years, finally rolling over into a runaway greenhouse effect just a few hundred million years ago.

In 2017, Elon Musk laid out his grand sweeping plans for the future of SpaceX, the company that would take humanity to Mars. Over decades, tens of thousands of Starship flights would carry a million human beings to the surface of the Red Planet, the minimum Musk expects it’ll take to create a self-sustaining civilization. The number of details in an effort like this is mind-boggling. What about the reduced gravity, radiation exposure, and space madness? What about return flights? Replacement parts? Building materials? What’s everyone going to eat?

On Saturday, September 28th, SpaceX CEO Elon Musk stood in front of an audience in Boca Chica, Texas, and presented the fully assembled SpaceX Starship, 50 meters tall and made from shiny stainless steel. As part of his presentation, Musk showed off the history of the company’s developments so far and gave us an updated view of what Starship and its first stage Superheavy booster will look like when they’re fully operational. It was actually a pretty short presentation, and there weren’t a lot of details. But he stuck around to answer questions from many space journalists, and we’ve got a much better idea about Starship and what happens next.

One of my most requested guests is Dr. Robert Zubrin, engineer and founder of the Mars Society. It was Dr. Zubrin's "Case for Mars" that helped inspire me to get into space journalism in the first place. We had a wide-ranging interview that updated the Case for Mars, looked at what comes next, and how current efforts are stumbling in their efforts to return humans to the Moon, and then on to Mars.

I’ve said many times in the past that the Earth is the best planet in the Universe. No matter where we go, we’ll never find a planet that’s a better home to Earth life than Earth. Of course, that’s because we, and all other Earth life evolved in this environment. Evolution adapted us to this planet, and it’s unlikely we could ever find another planet this good for us. However, is it the best planet? Are there places in the Universe which might have the conditions for more diversity of life?

Humans to Mars. That’s the plan right? The problem is that sending humans down to the surface of Mars is one of the most complicated and ambitious goals that we can attempt. It’s a huge step to go from low Earth orbit, then lunar landings, and then all the way to Mars, a journey of hundreds of millions of kilometers and 2 years at the least. But there are two places humans can go which are a stepping stone between Earth and Mars. Base camps that would let us gather our resources in relative safety before dropping down into that gravity well. I’m talking about the moons of Mars: Phobos and Deimos.

We’re learning more and more about extrasolar planets, and for the first time, astronomers have discovered water vapor in the atmosphere of a planet orbiting another star. The planet is located in the habitable zone of its star, so this might even be rain. Of course, it’s not all good news, it’s much more massive than Earth, with higher gravity, and is probably bathed in radiation from its red dwarf star. But, it’s a good start in the search for habitable places in the Universe, places where there might be life.

Lagrange Points. Stable spots in space that you just can’t stop thinking about. What spacecraft work best in which places? What are some amazing ideas that could utilize these regions across the Solar System? In the last episode, I gave an overview of the Lagrange points, and then went into the details of spacecraft missions sent to L1, the perfect place to constantly observe the Sun, the Earth, or to block radiation coming from the Sun. The best place for a lunar elevator, or a spot to put a space station at the Moon. This week, we’re going to talk about L2 and L3, the other meta-unstable spots that you can park a spacecraft at.

Thanks to gravity, there are places across the Solar System which are nicely balanced. They’re called Lagrange Points and they give us the perfect vantage points for a range of spacecraft missions, from observing the Sun to studying asteroids, and more. Various spacecraft have already visited Lagrange Points, used them for some or all of their missions, and there are fascinating plans in the works that could put new missions and even space colonies into these balanced places in the Solar System. Let’s explore the Lagrange Points.

One of the great accomplishments of the Apollo missions was to bring home hundreds of kilograms of lunar rock. Suddenly, geologists had a lifetime’s worth of lunar samples captured from several different spots across the Moon. These rocks and dust have been under continuous analysis since the Apollo 11 astronauts came home over 50 years ago. And they’re still making discoveries. Scientists have samples of the Sun’s solar wind, particles from a comet’s tail, a few grams from an asteroid, with more coming shortly. But there’s one world, the focus of so much scientific study, which has never had a sample returned: Mars. NASA and the European Space Agency have been making plans to bring a sample home from Mars for decades, and now, missions could fly in the next few years, finally bringing a chunk of the Red Planet home to Earth for us to study directly.

As I’ve mentioned in several episodes now, humanity is in a bit of a transition period, a time when it makes sense to launch material up and out of Earth’s gravity well into orbit, and beyond. But it’s really expensive, costing up to $10,000 per pound you want in orbit, and 10 times if you want it on the Moon. But over the coming decades, more and more of our space-based infrastructure will be built in space, manufactured out of materials that were mined in space. The only thing that’ll actually need to leave the Earth’s clingy gravity well will be us, the humans, the tourists, wanting to visit all that space infrastructure. Of course, in order to achieve that space future, engineers and mission planners will need to design and construct the technology that will make this possible. That means testing out new prototypes, technologies and methodologies for mining and space-based manufacturing.

Mars is the place that most of our spacecraft, landers and rovers are studying, searching for any evidence that life ever existed somewhere else in the Solar System. But talk to planetary scientists, and they’re just as excited about the ocean worlds of the Solar System; the moons, asteroids, dwarf planets and Kuiper Belt objects where there could be vast oceans of liquid water under thick shells of ice. The perfect environment for life to thrive. We’ve only had tantalizing hints that these oceans are there, but NASA is building a spacecraft that will study one of these worlds in detail: the Europa Clipper. And they’re not the only ones. The European Space Agency is building their own mission, the Jupiter Icy Moons Explorer.

On Tuesday, July 30th, NASA announced 19 different partnerships with 13 different companies to use their expertise to help them develop space technologies, from advanced communications systems to new methods of entry, descent and landing. Instead of contracting out specific projects, NASA will make its employees, facilities, hardware and software available to these companies, for free. One of the most notable of these partnerships will be with SpaceX and NASA’s Glenn and Marshall Centers to help advance the technology of transferring propellant in orbit. In other words, NASA is going to help SpaceX figure out how to refuel a spacecraft while it’s in space. And if they can figure this out, it could completely change the way missions are launched and flown.

It’s amazing to think there are telescopes up in space, right now, directing their gaze at distant objects for hours, days and even weeks. Providing a point of view so stable and accurate that we can learn details about galaxies, exoplanets and more. And then, when the time is up, the spacecraft can shift its gaze in another direction. All without the use of fuel. It’s all thanks to the technology of reaction wheels and gyroscopes. Let’s talk about how they work, how they’re different, and how their failure has ended missions in the past. 06:49 Scientists May Have Figure Out Why So Many Spacecraft Were Failing - https://www.youtube.com/watch?v=KibT-PEMHUU Our Book is out! https://www.amazon.com/Universe-Today-Ultimate-Viewing-Cosmos/dp/1624145442/ Audio Podcast version: ITunes: https://itunes.apple.com/us/podcast/universe-today-guide-to-space-audio/id794058155?mt=2 RSS: https://www.universetoday.com/audio What Fraser's Watching Playlist: https://www.youtube.com/playlist?list=PLbJ42wpShvmkjd428BcHcCEVWOjv7cJ1G Weekly email newsletter: https://www.universetoday.com/newsletter Weekly Space Hangout: https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/ Astronomy Cast: https://www.youtube.com/channel/UCUHI67dh9jEO2rvK--MdCSg Support us at: http://www.patreon.com/universetoday More stories at: http://www.universetoday.com/ Twitch: https://twitch.tv/fcain Follow us on Twitter: @universetoday Like us on Facebook: https://www.facebook.com/universetoday Instagram - https://instagram.com/universetoday Team: Fraser Cain - @fcain / frasercain@gmail.com Karla Thompson - @karlaii / https://www.youtube.com/channel/UCEItkORQYd4Wf0TpgYI_1fw Chad Weber - weber.chad@gmail.com References: https://www.nature.com/news/the-wheels-come-off-kepler-1.13032 http://www.planetary.org/blogs/jason-davis/lightsail-2-successful-flight-by-light.html https://astrobites.org/2013/05/21/kepler-reaction-wheel-failure-cripples-spacecraft-but-mission-thrives/ https://www.nasa.gov/mission_pages/dawn/news/dawn20120418.html https://www.jpl.nasa.gov/blog/2016/1/dawns-sunny-side-views-of-dwarf-planet-ceres/#RWAs https://www.youtube.com/watch?v=KibT-PEMHUU https://www.spacetelescope.org/announcements/ann1818/ https://jwst.nasa.gov/content/forScientists/faqScientists.html#wheels https://www.youtube.com/watch?v=DFmOr1vMOT4

NASA’s Transiting Exoplanet Survey Telescope launched back in April, 2018. After a few months of testing, it was ready to begin mapping the southern sky, searching for planets orbiting stars relatively nearby. We’re just over a year into the mission now, and on July 18th, TESS has shifted its attention to the Northern Hemisphere, continuing the hunt for planets in the northern skies. As part of this shift, NASA has announced a handful of fascinating new planets turned up by TESS, including a couple of worlds in categories which have never been seen before.

When we look outward into space, we’re looking backwards in time. That’s because light moves, at the speed of light. It takes time for the light to reach us. But it gets even stranger than that. Light can be absorbed, reflected, and re-emitted by gas and dust, giving us a second look. They’re called light echoes, and allow astronomers another way to understand the Universe around us.

There are few places in the Solar System which are as fascinating as Saturn’s moon Titan. It’s a world with a thicker atmosphere than Earth. Where it’s so cold that it rains ammonia, forming lakes, rivers and seas. Where water ice forms mountains. Like Europa and Encleadus, Titan could have an interior ocean of liquid water too, a place where there might be life. Titan’s got layers, and fortunately, there’s an awesome new mission in the works to explore it: the Titan Dragonfly mission.

As NASA prepares to return to the Moon by 2024 as part of its Artemis program, the agency is focusing its efforts on exploring the Moon’s polar regions. These are areas of the Moon which seem to have a lot of water mixed in with the regolith. Some of these craters are permanently in shadow, and might still have large quantities of water, that’s accessible to human and robotic explorers. This is a critical resource, and the Moon might be just the place to help humanity as it pushes out to explore the rest of the Solar System. But it might also be an illusion. We really won’t know until we look up close.

Where you can travel in space depends on how much propellant you’ve got on board your rocket and how efficiently you can use it. But there’s a source of free propellant right here in the Solar System - the Sun - which is streaming out photons in all directions. You just need to catch them. And right now, the Planetary Society’s new LightSail 2 spacecraft is testing out just how well it’ll work.

On October 19th, 2017 astronomers detected the first interstellar asteroid (or maybe comet) passing through the Solar System: Oumuamua. It had a brief encounter with the inner Solar System and then hurtled back out into interstellar space. Once astronomers noticed it, they directed the world’s telescopes on the object, but it was too far away to reveal anything more than a faint dot. Until now, we’ve only been able to study objects in our own Solar System. We have no idea what the rest of the Milky Way is like. But we were too late to catch it, no spacecraft was ready to make a quick intercept. Well, scientists aren’t going to make that mistake again. The European Space Agency announced their plans to build a comet interceptor. A spacecraft that will lurk out at the Earth-Sun L2 Lagrange point, waiting for a long-period comet or interstellar object to pounce on, and give us the first close up view ever.

But the reality is that life itself has been broadcasting the existence of life on Earth for 500 million years. Blame it on the plants. In addition to filling the atmosphere with oxygen, plants give off a very specific wavelength visible in infrared radiation. It’s the kind of signal that other civilizations could search for as they’re scanning the galaxy. It’s what we’ll be looking for too. But don’t just blame the plants. Other forms of life have been giving off signals too, signals we can search for as we discover new exoplanets and wonder if they have life there.

This past weekend Skylias moderated a debated between John Michael Godier and Fraser Cain over their Fermi paradox theories. If there are aliens where are they? The Fermi paradox theory asks where are the alien civilizations in the galaxy? And in the universe. If they exist. Where are the extraterrestrials? Website: https://www.eventhorizonshow.com/

The Solar System is a really big place, and it takes forever to travel from world to world with traditional chemical rockets. But one technique, developed back in the 1960s might provide a way to dramatically shorten our travel times: nuclear rockets. Of course, launching a rocket powered by radioactive material has its own risks as well. Should we attempt it?

Explorers have always brought stowaways with them on board. Thanks to our travels around the world, hardy creatures like rats, goats, pigs and starlings and more have found their way to every corner of the globe. Not to mention our plants, microbes and viruses. Wherever we go, life goes with us, whether we want it to or not. And when we travel to other worlds, it looks like the most extreme life Earth has ever cooked up is ready and willing to make the journey with us. Now that the big flybys are over, it’s time to dig into the regolith, search for life in underground lakes and oceans, return samples back to Earth. We’re going to give life every opportunity to contaminate other worlds. What can we do to prevent it?

This week, my guest will be science writer and futurist George Dvorsky, from Gizmodo and io9.

In this week's questions show, I wonder if planets could form from the wreckage around dead stars, who don't all stars collapse immediately into black holes, and where did my new channel pic come from?

Today I'm joined by Chad Weber, the video editor for the Guide to Space and other videos we do here on Universe Today. Chad was also the audio editor for Astronomy Cast and other Astrosphere projects.

All that waiting has paid off. Here it is, the first ever image of a black hole.

We now know of thousands of confirmed exoplanets, with many more candidates. And there are now dozens of planet hunting telescopes on Earth and in space, using a range of techniques to find tens of thousands more. There’s a new class of instruments and missions in the works that’ll give us an incredible understanding about the planets orbiting other stars. One of these will be the one to find Earth 2.0.

My guest today will be Dr. Brian Keating, a professor of physics and the author of the recent book "Losing the Nobel Prize". Brian was on the BICEP2 team that announced the discovery of primordial gravitational waves; a discovery that turned out to be dust.

In this QA episode, I wonder if there could be a galactic panspermia, why I'm always stealing articles from Fraser Cain from Universe Today, and where the Universe came from.

My guest today will be Dr. Ian O'Neill. Ian is an astrophysicist and journalist, and has been covering space and astronomy news for more than a decade.

This week I'm joined by Frank White, author of the Overview Effect. His new book is the Cosma Hypothesis, which talks about humanity's role in the larger cosmos.

Aircraft make some of the best platforms for science here on Earth. From weather balloons to study the high atmosphere to aircraft that fly into the hearts of hurricanes. From surveys of Antarctic ice sheets to drones.

In this week's QA, we discuss infecting Mars with diarrhea, if life evolved more than once, and why other countries don't help explore space.

It’s too bad Mars is such an interesting place, because it’s actually one of the most difficult places to visit in the Solar System, especially if you want to bring along a lot of luggage. That planet is a graveyard of missions that didn’t quite make it.

This week's guest is Dr. Jessie Christiansen, aka the Aussie Astronomer. Jessie is an exoplanet researcher working at NASA's Exoplanet Science Institute at Caltech. We'll talk all things exoplanets.

I was a guest on the Space Junk Podcast from Oceanside Photo and Telescope. Subscribe to their podcast! When it comes to end of the world theories, NASA conspiracies or astronomy hoaxes Fraser has seen or heard them all. This episode picks apart those ideas and we talk about whether anything should or could be done to combat them.

My guest today is Phil Torres, author, journalist and the founder of the X-Risks Institute. He tracks the ways the world could end. He's the author of Morality, Foresight and Human Florishing. An Introduction to Existential Risks

This week I'm joined by Dr. Morgan Rehnberg. Morgan is a planetary scientist, scriptwriter for SciShow Space, and of course, one of the co-hosts of the Weekly Space Hangout.

In this week's QA, I answer if Opportunity could ever phone home, are there stars between galaxies, and who, exactly, is Chad? Featuring a special guest answer from Dr. Becky.

Today I wanted to look back at the history of the Mars Exploration Rovers, Spirit and Opportunity. To take you through their creation, launch to Mars, the amazing discoveries they made, and of course, how they finally died.

Dr. Kimberly Cartier is an exoplanet researcher, reporter for Eos Magazine and one of my co-hosts with the Weekly Space Hangout. Join us for a conversation about space, astronomy and the search for extrasolar planets.

In this week's questions show, I explain why SLS is still happening, if we can rule out contamination when we finally find life, and wonder why China is sending spacecraft to the Moon.

Today Fraser is joined by exoplanet researcher Dr. Jason Wright from Penn State University. In addition to the more traditional hunt for exoplanets, Jason is helping define the search for extraterrestrials using all the new techniques available to astronomers.

In this week's QA, I wonder if there were other bombardments, how the Earth could have been oxygen rich, and why the asteroid belt isn't a planet. With a special guest answer from Tim Dodd, the Everyday Astronaut.

Astronomers working with the NASA’s Chandra X-Ray Observatory and ESA’s XMM-Newton have developed a technique to watch quasars and track the expansion of the Universe over the last 9 billion years. What they found is that the mysterious dark energy that’s currently accelerating the expansion of the Universe doesn’t appear to be a fixed amount. It’s changing, and appears to be increasing over time. If true, it’s a groundbreaking discovery in cosmology, and it could just fortel the end of the Universe.

Today I hang out with astronomer Dean Regas, author with the Cincinnati Observatory and author of 100 Things to See in the Night Sky.
