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.
