Amanda Karakas and Chiaki Kobayashi - All the Gold in the Universe - Astronomy News with the Cosmic Companion Oct 6, 2020
How was gold formed? Dr. Amanda Karakas of Monash University and Dr. Chiaki Kobayashi of the University of Hertfordshire talk about their work showing how most of the gold in the Universe was formed.
Hello everyone!
This is a very special global episode on Astronomy News with The Cosmic Companion, as we talk with Dr. Amanda Karakas of Monash University, speaking from Melbourne, Australia, as well as Dr. Chiaki Kobayashi, from the University of Hertfordshire, joining us from London. These researchers were at the heart of the new study showing how much of the gold in the Universe was produced by a particular type of supernova explosion.
But first, we examine a stunning glitter seen around a supermassive black hole. We also journey to Mars, where the Mars Express Orbiter finds three more salty lakes beneath the surface of that world. The Red Planet is also an easy find in the sky this week, and we will take a look at how to find it. We will then journey back in time, where (and when!) we will see six galaxies huddling around an ancient quasar, and learn how the largest structures in the Universe were formed.
