Does HD 106906 b resemble Planet X? - Dr. Paul Kalas, astronomer, UC Berkeley - Astronomy News with The Cosmic Companion Dec. 22, 2020

For this final episode of our third season, we welcome Dr. Paul Kalas from UC Berkeley to the show. He is an astronomer studying the exoplanet HD 106906, which might resemble an unseen ninth planet in our own solar system.But first, we journey far out in space and back in time, as astronomers lay their sights on the most distant – and oldest – galaxy ever seen. Closer to home, we examine the discovery of hexamine – a chemical critical to the development of life – inside an asteroid. Finally, we listen in on radio waves from the exoplanet Tau Boötis b, and learn how it shows the first-ever evidence for a magnetic field surrounding a planet in an alien solar system.--- Send in a voice message: https://anchor.fm/the-cosmic-companion/messageSupport this podcast: https://anchor.fm/the-cosmic-companion/support This is a public episode.
