Exoplanet K2-18b

from Ai Decodes · host Albany Adams

Let's talk about K2-18b, a distant exoplanet orbiting within its star's habitable zone. Initial observations with the Hubble Space Telescope indicated the presence of water vapor, and later James Webb Space Telescope (JWST) data revealed methane and carbon dioxide, suggesting it could be a Hycean world with a hydrogen-rich atmosphere and a possible water ocean.
