“Project Hail Mary” is finally in theaters, and the science is just as thrilling as the story. This week on Planetary Radio, Sarah Al-Ahmed and senior communications adviser Mat Kaplan share their first reactions fresh from the theater. Author and producer Andy Weir tells us in his own words what the story is really about, in a flashback conversation with Mat. Award-winning Nature correspondent Alexandra Witze takes a critical scientific eye to the film. Virginia Tech astrophysicist Nahum Arav walks us through the real-life fate of our Sun. And in What's Up, Bruce Betts joins us to explore just how long it would actually take humanity to reach Tau Ceti at the fastest speed a spacecraft has ever traveled.
