In this week's questions show, I wonder what would happen if SpaceX failed as a company, why New Horizons can't search for Planet 9, and I ask for your suggestions for new names to call dark matter and dark energy. Support Universe Today Podcast
Professor Avi Loeb is one of the hardest working astrophysicists in the field, writing a blistering number of academic papers on fascinating topics like the Fermi Paradox, the habitability of other worlds, black holes, and the history of the early universe. He's also one of the people working on the Breakthrough Starshot project to send tiny probes to other star systems. Support Universe Today Podcast
On this week's live QA, I got a chance to talk with David Brin, a science fiction author, futurist, and an advisor for NASA's Innovative Advanced Concepts awards. David and I talked about the Transparent Society, why we should go to asteroids before the Moon or Mars, and some cool ideas coming out of NIAC. Support Universe Today Podcast
This week Professor Brad Peterson joins me to talk about the capability of the LUVOIR telescope, which is one of the next generation space telescopes NASA is considering as part of its new Decadal Survey. Support Universe Today Podcast
In this week's QA, I explain why dark matter is really a thing, and not just some made up thing by evil astronomers. How event horizons flatten out when they spin, what kind of scientist I'd want to be, and if you could build a ladder to space. Support Universe Today Podcast
Just me again, back from Australia answering live questions about the Universe. Support Universe Today Podcast
Astronomers have finally solved one of the outstanding mysteries in cosmology. Forget about all the dark matter and dark energy, where’s all the missing regular mass in the Universe? This has been called the “missing baryon problem”. Support Universe Today Podcast
In this week's question's show, I answer what would happen if the Milky Way lost its supermassive black hole, why can't you spiral stuff into the Sun, why do we assume life breathes oxygen? Support Universe Today Podcast
Until we learned to properly navigate our way across the oceans, early explorers were fearful to lose sight of land in case they’d be lost at sea. They learned to use the water currents, winds, movements of birds and of course, the positions of the Sun, the Moon and the stars to find their way across the seas to distant lands. As we learned to launch spacecraft into orbit and out into the Solar System, mission planners needed to develop entirely new methods of navigation. Support Universe Today ...
In this week's episode, I explain why you can't just calculate the position of Planet 9, why we don't use parachutes to retrieve boosters, and if we can wait 100 million years to see the Great Attractor. Support Universe Today Podcast
For the first time ever, astronomers have captured a direct image of a newly forming planet orbiting around a newly forming star. It’s a stunning photograph, not only for the science and what was observed, but what it means the future of exoplanetary astronomy. Support Universe Today Podcast
Live QA with just Fraser this week. Support Universe Today Podcast
Rocket launches are expensive. Even with huge price drops from SpaceX and other New Space companies, there’s no cheap way to get stuff down here in Earth’s gravity well up to low Earth orbit. In order to really survive and thrive in space, we’ve got to learn to live off the land, to acquire the resources in space that will allow us to survive… in space. We’ve got to learn to turn those raw materials into forms we need: fuel, breathable air, water, construction materials, and eventually even fini...
In this week's questions show, I answer if it's a good idea to build a space internet, if microbes reach Mars, will they evolve into something new, where could we go after Mars, and more. Support Universe Today Podcast
This week I'm joined by my Astronomy Cast co-host Dr. Pamela Gay to talk about all things astronomy, and casting. Support Universe Today Podcast
In this week's QA, I present real pictures of the whole Earth, not some fake CGI, and wonder if Jupiter could be used as a gravitational lens for a space telescope. Support Universe Today Podcast
In this week's live QA, I was solo again, answering live questions from the audience about Trump's ongoing plans to build a Space Force. Support Universe Today Podcast
In this week's questions show, I explain how we now where gravitational waves are coming from, will there be planets around a white dwarf, what does it feel like where the space station is getting boosted, and if I'm an arrogant fool. Support Universe Today Podcast
The Hubble Space Telescope has been in space for 28 years, producing some of the most beautiful and scientifically important images of the cosmos that humanity has ever taken. But let’s face it, Hubble is getting old, and it probably won’t be with us for too much longer. Support Universe Today Podcast
This week, it's a live QA with radio astronomer Dr. Nicole Gugliucci to talk about radio telescopes, and how close the movie Contact is to reality. Support Universe Today Podcast
Space is the worst. It’s got hostile radiation, a total lack of atmosphere, near absolute zero temperatures, problematic gravity wells, and worse. In order to keep your spacecraft alive in that environment, you need electricity to keep it warm. Not to mention all the power to run scientific instruments and the transmitters to send that data home. Getting enough power in space is a big problem. Support Universe Today Podcast
In this week's questions show, I talk about entry level telescopes, why we can see galaxies billions of light years away but not objects on the Moon, and why events that won't happen billions of years into the future still make us kind of sad. Support Universe Today Podcast
Paul was busy last week, but now he's ready to join me for an hour answering your mind bending questions about space and astronomy. Bring all your complex questions about dark matter, black holes and the Big Bang and he'll sort it all out. Support Universe Today Podcast
Humans are believed to be the most technologically advanced civilization that’s ever set foot on Earth, or really anywhere in the Solar System. But are we the first? Support Universe Today Podcast
In this week's questions show, astronaut Mike Massimino answers a question about astronaut training, I wonder how we could survive if the Sun dies, and explain why the shuttle's fuel tank was orange. Support Universe Today Podcast
In my opinion, Eric Berger (aka @sciguyspace) is one of the top journalists working on stories about spaceflight, especially SpaceX, Blue Origins and NASA. Eric will join me live to answer your questions about the state of private and public space exploration. Support Universe Today Podcast
The observable Universe is finite, which means there are limits to what we can see, now and deep into the future. Dr. Paul Sutter joins Fraser to talk about the various cosmological horizons that surround us. Support Universe Today Podcast
It was just me this week, answering questions from the YouTube audience. Support Universe Today Podcast
In this week's questions show, the viewers try to suggest names for balloon rockets. Could live from Venus escaped to Earth? Is the Fermi Paradox really a paradox when we've only explored a little bit of the galaxy? And More Support Universe Today Podcast
People always ask me why we’re stuck with chemical rockets. Seriously, exploding a bunch of hydrogen or kerosene is the best we can do? Support Universe Today Podcast
