Roberto Gilli - Six Galaxies Orbiting an Ancient Supermassive Black Hole - Astronomy News with the Cosmic Companion Oct 20, 2020
A cluster of galaxies huddle around a galaxy in the ancient Universe, allowing us to see a baby picture of the largest structures in the Cosmos
Hello everyone!
This week, we are joined by Dr. Roberto Gilli from the National Institute of 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, learning how to see a meteor shower happening this week.

Coming Up:
October 27: Dr. Meridith Joyce of Australian National University. We will talk about her work finding the star Betelgeuse is both closer, and smaller, than astronomers believed.
