Hello everyone! Hello and welcome back to The Cosmic Companion. This week, we are happy to be joined by Dr. Kathryn Zurek, Theoretical Physicist at Caltech, talking about how dark matter may be detected here on Earth by looking for subatomic particles called magnons.But first, we look up at Comet NEOWISE visiting the Earth this month, and we say hello to stars from another galaxy which moved into the Milky Way billions of years ago. We hear the story of astronomers scrambling to view a short radio burst from the ancient Universe before it disappeared, we examine the origins of water here on Earth, and look at the closest pictures ever taken of our Sun.Watch the video version of this episode:Dr. Kathryn Zurek of Caltech talks about dark matter on Astronomy News with The Cosmic Companion.This podcast is also available from all major podcast providers.Coming July 28: Dr. Lina Necib, Post-doctoral Researcher at Caltech, who recently discovered Nyx stars – visitors from outside the Milky Way.Coming August 4: Dr. Laurent G.J.
