In this week's live QA, I talk about how much oxygen we need to survive. Could SpaceX have succeeded without NASA's help? And what's going to happen with Gateway with all the changes to Artemis?

Dr. Peter Woit is a theoretical physicist and senior lecturer in the math department at Columbia University. He's a critic of string theory, wrote a book called "Not Even Wrong" and maintains a blog of the same name.

In this week's live QA, I talk about Elon Musk's hope of establishing a free Mars, the future of gravitational wave detectors, and what do I think about trying to live in other places in the Solar System?

In this week's questions show, I talk about the Dark Forest theory in the Three-Body Problem series of books. Is it a compelling answer to the Fermi Paradox? How much of a risk is dust to interstellar travel? Is black hole evaporation negated by black holes absorbing additional material and energy?

This week my guest is Australian astronomer Fred Watson. He's a writer, researcher and Australia's Astronomer at Large.

In this week's live questions show, I talk about the possibility of life on exomoons and why they'll be important targets to search. Why I hate the embargo system for news, and the announcement of water on the Moon.

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.

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

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

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.
