Universe Today Podcast

In this week's live QA, I give updates on the discovery of phosphine at Venus, how the Universe could be compressed into a singularity leading to a Big Bang, and more...

This week I'll be talking Dr. Seth Shostak from the SETI Institute about his work searching the Universe for evidence of extraterrestrials. Check out Seth's podcast at: http://radio.seti.org/

Here's a guest interview I did with Ralph Crewe on his podcast "Isn't That Something" talking about the 2020 Mars Opposition. Check out the podcast at: https://ralphcrewe.podbean.com/

In this week's live questions show, I answer questions about drilling for microbes on Mars, missions that could survive the surface of Venus, and if anyone else is dissatisfied with the Big Bang.

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.

This week I'll be talking with astronomer Scott Gaudi from Ohio State University about the search for habitable exoplanets and NASA's HabEx mission.

Did Venus life hitch a ride on the Venera missions? Could we use life to terraform Venus? Life on Venus? Booooring.

In this week's live QA, I answer more questions about the discovery of phosphine on Venus, does Russia own Venus? And more...

It's time for an all new season of Open Space. This is a live QA with Fraser Cain.

Obviously, everyone wanted to discuss the discovery of phosphine in the atmosphere of Venus. So we did that as well as talk about the progress of Starship and upcoming missions to Mars.

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.

In this week's questions show, I wonder about the supernova that formed the Solar System, how astronauts deal with air pressure differences, and how we're going to handle the cold temperatures on Mars.

In this week's questions show, you wondered if the simulation hypothesis is a good answer to the Fermi Paradox. How to get a career in space manufacturing? Will a compass work on Mars? And more...

In this week's questions show, I consider what the benefits might be to humanity if we discover that we aren't alone in the Universe. How long did Mars planetary dynamo take to turn off? Could we find and repair the lunar rovers?

In this week's questions show, I explain how it's possible for stars to orbit so closely they're actually touching. What are the limits to gravitational slingshots, and how astronomers know where to point their telescopes in the Universe.
