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

We talk to Martian geologist Dr. Kirsten Siebach of Rice University about her work finding that Gale Crater on Mars once resembled Iceland.

This week, we talk to Dr. Kirsten Siebach, Martian geologist from Rice University, talking about her work uncovering secrets of the climates of ancient Mars.

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.
