"Potential for Warm Oceans on Dwarf Planets at Solar System's Edge"

Scientists using the James Webb Space Telescope have found evidence suggesting that the dwarf planets Eris and Makemake, located in the Kuiper Belt, may have underground oceans of liquid water due to geothermal activity. Observations indicate that methane on their surfaces is likely produced from within the planets' rocky cores, pointing to potential sources of liquid water beneath their icy surfaces. The findings raise the possibility of these dwarf planets containing habitable oceans and could also apply to Saturn's moon Titan, potentially impacting its presumed habitability.
