Are there aliens on exoplanet K2-18b? Scientists just scanned it for signals

K2-18b has become one of the most closely watched exoplanets in recent years. The planet lies about 124 light years away in the constellation Leo and orbits within the habitable zone of a red dwarf star. Observations from the James Webb Space Telescope have revealed an atmosphere rich in carbon dioxide and methane, making K2-18b one of the leading candidates for a "Hycean" world, where a thick hydrogen rich atmosphere may surround a global ocean of liquid water.
