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 also 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.--- Send in a voice message: https://anchor.fm/the-cosmic-companion/messageSupport this podcast: https://anchor.fm/the-cosmic-companion/support Get full access to The Cosmic Companion at thecosmiccompanion.substack.com/subscribe
