Webb Finds Evidence of Hydrothermal Processes in Interiors of Eris and Makemake
The icy dwarf planets Eris and Makemake have surfaces bearing methane ice of unknown origin. According to an analysis of data from the NASA/ESA/CSA James Webb Space Telescope, Eris and Makemake have rocky cores that underwent substantial radiogenic heating and may still be warm/hot enough to make methane. Glein et al. found evidence for hydrothermal
