Roberto Gilli - Finding Six Galaxies Orbiting an Ancient Black Hole - The Cosmic Companion October 20, 2020

This week, we are joined by Dr. Roberto Gilli from the National  Institute for Astronomy and Astrophysics, speaking with us from Italy.  We will talk about his recent discovery of six galaxies huddled around a  supermassive black hole in the early Universe.   But first, we take a look at the massive red giant star Betelgeuse,  finding it's not as big –or as close to exploding – as we thought.  Speaking of exploding stars (because, why not?) we take a look at a pair  of massive stars doomed to end their lives in a dramatic fashion. And,  we will take a look up at our night sky, and learn how to see a meteor  shower happening this week.--- Send in a voice message: https://anchor.fm/the-cosmic-companion/messageSupport this podcast: https://anchor.fm/the-cosmic-companion/support This is a public episode.
