Episode Description from the Publisher

What do you call a very-but-not-so-supermassive black hole completely encased in a warm dense cloud of hydrogen? A hot mess? How about "black hole star", a new category of crazy astronomical object that can explain some of the James Webb Space Telescope's mysterious findings from the early universe. And we're a step closer to understanding our own star with dazzling data from the Inouye Solar Telescope that shows evidence of a fluid instability at the surface that helps explain how the solar corona gets so hot. Join us for this, space news, sci fi trivia and more.
