This is an unusual interview for my channel. It's mostly about AI, our current developments and the threats it poses to us.

What's the maximum speed you can get from a gravity assist? Can we have a double gravitational lens? What do you need to do to a phone to sent it to space? Answering all these questions and more in this week's Q&A show.

Polaris Dawn launches and completes the first private spacewalk, the surface of a giant star is resolved with incredible detail, Starliner comes home empty, and amazing new images of Mercury from BepiColumbo.

Stars oscillate. Even the Sun does. And we can learn a lot about them by studying those oscillations. How is it done and what can we learn? Finding out in this interview.

What would it take to bring the Voyagers back to Earth? When will we see a true deep field by Webb? Why is Europa Clipper solar-powered? Why do black holes rotate? Answering all these questions and more in this week's Q&A show.

Another asteroid hit exactly where astronomers predicted, a monster asteroid rolled Ganymede over onto its side, strange sounds coming from Starliner, and China announces when it’ll try to grab a piece of Mars.

Interferometers are a great tool for getting incredible resolution without building giant mirrors. Why don't all telescopes use it? What projects should we expect and what could we get from them? What are the challenges? Finding out in this interview!

Could entangled electrons be used for FTL communications? Will Starship enable better satellites? Could we detect radiation on another world? Are there alternative explanations for black holes? Answering all these questions and more in this week's Overtime Q&A.

Is Betelgeuse a binary star? Starliner is coming home empty. New Glenn is on schedule to launch NASA’s next mission to Mars. NASA’s solar sail unfurls.
