Exploring the Climates of Ancient Mars - Dr. Kirsten Siebach, Rice University, Astronomy News with The Cosmic Companion Jan 26, 2021

<p>This week, we talk to Dr. Kirsten Siebach, a Martian geologist from Rice University, talking about her work uncovering secrets of the climate of ancient Mars.</p> <p>But first, we study a newly-discovered system of exoplanets featuring an extreme planet of molten lava. Next, we learn about a so-called cotton-candy planet with a density so low it wasn't thought to be possible. Finally, closer to home, we take a look at a new study revealing that Gale Crater on Mars may have once resembled Iceland, before talking to one of the lead researchers on that study.</p> <p>Next week, we talk to Dr. Lauren Weiss, astronomer at the University of Hawaii, on her work studying the TOI-561 solar system and extreme exoplanets!</p> --- Send in a voice message: https://anchor.fm/the-cosmic-companion/message Support this podcast: <a href="https://anchor.fm/the-cosmic-companion/support" rel="payment">https://anchor.fm/the-cosmic-companion/support</a>
