38: Blue Twinkly Supergiants

Our Sun is a star, and because it's so close and familiar, we think that's what stars are like. But there are loads of different kinds of stars out there — small ones, cold ones, hot ones, wobbly ones, and really stupidly BIG ones. Emily gets excited in this episode because new research on Blue Supergiant Stars shows they wobble and wiggle, and that can tell us loads about how stars evolve.
