In this episode, we'll be covering a wide range of topics, from the study of the inside of our own world, to the discovery of new worlds with two stars. Along the way we'll visit Ceres, the sleeper pick of formerly habitable worlds, and take a look into Mellitic Acid, one of the most stable molecules to form protocells. Follow along as we go from beneath our feet to above our skies! Original Sources: Ceres: https://doi.org/10.1126/sciadv.adt3283 A Decade of Global Water Cycle Monitoring: NASA...
