A new investigation with NASA’s James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. Webb’s discovery adds to recent studies suggesting that K2-18 b could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface.
That was my first thought. That doesn’t mean there couldn’t be microbial life there though. One of the gases being released, or supposedly released is mostly made by phytoplankton here. So if anything this may confirm microscopic life forms on other planets.
Maybe super mini crab or slug people.
