Episode 499 - Air and atmospheres on exoplanets

September 5, 2022

CO2 gets a lot of bad press on earth, but in space, it could actually be incredibly helpful. On Mars, the Perseverance mission turned CO2 into Oxygen just like a tree. Making air on Mars requires a bit of Moxie and Perseverance. Mar's atmosphere may be thin, highly variable and full of CO2 but it can be harnessed to produce Oxygen. Could future mission to Mars make their own oxygen on the surface of Mars? Finding CO2 on exoplanets has been incredibly hard but the JWST helps shed light on this universal gas. Incredible hot, massive but not super dense, the Hot Jupiter WASP-39b becomes the latest target of the JWST. What can a hot Jupiter like WASP-39b teach us about exoplanet formation?
