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

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