Hello everyone!

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.

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.
