Universe Today Podcast

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 hea…

Another week, another Open Space. In this week's questions show, I talk about planets orbiting red dwarf stars, if planets could steal moons from each other, and whether or not the space shuttle shou…

In this week's episode of Open Space, I talk with Dr. Jamie Molaro, a planetary scientist who helped discover that the surface of asteroid Bennu has rocks that crack because of the constant day/night…

Another week, another Open Space. This week I answer questions about what we might see in the next 5 decades. When dark matter will get debunked, and who will carry the Mars torch after Elon Musk pas…

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 …

In this week's questions show, I answer questions about how the International Space Station stays above the Earth's atmosphere, does dark matter need a better name? And how do astronomers know they'r…

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 Spa…

In this week's questions show, I answer whether or not dark matter could become a black hole, how do we know the Universe is flat, and what would happen to the world's market for precious metals once…

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 …

In this week's live QA, I explain why a black hole can have infinite density but not infinite gravity. Does your perception of time change due to your mass, and am I ever intimidated by the people I …

On a special time, we've got a special guest, Professor Martin Rees, a British cosmologist and astrophysicist. He's the Astronomer Royal and helped develop many of the modern theories of astronomy an…

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…

This week's guest is Moiya McTier. You might know Moiya as one of the regular co-hosts on the Weekly Space Hangout. She's an astrophysicist and science communicator, working with Columbia's Cool Worl…

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 …

In this week's live QA, I explain what's happening with Universe Today during the megavirus, what I think about the recently released UFO videos, how aliens could hide their existence, and if Starshi…
