Data collected by the James Webb Space Telescope shows that, like Pluto, the dwarf planets Eris and Makemake could be geologically active, which changes what we know about their chances of harboring life.
So that’s also studies by astrobiologists looking at atmospheric methane because we know it can be created in large quantities by metabolism in an organism in addition to non organic processes, and in the atmosphere it reacts to sunlight so it needs to be replaced to stay present in large quantities.
This is something different where they’re looking for chemical signatures, primarily methane, indicating geothermal vents which we’ve seen providing the energy to sustain life on earth at the bottom of the ocean. If abiogenesis requires some non organic processes like sublimation, evaporation, heating up and cooling down, etc to allow a self repeating process to start and continue to hold form until it’s able to use sugars to continue to maintain itself instead of depending on its environment to kick start the life process then you’ll want to look for those phase changes or boundaries like water/atmosphere or extreme heat/cold to provide the gradient that natural process may need like those studied in systems chemistry.
Why methane specifically?
