Could James Webb detect alien life on Hycean planets?
The James Webb Space Telescope could detect life in Hycean planets within the next few years. Hycean planets are exoplanets with liquid water oceans surrounded by hydrogen/helium atmospheres. Hycean planets are a sub-class of « mini-Neptunes » that could contain biomarkers in their atmospheres. Simulations by a team from Cambridge University show that these planets could be detected by JWST in just the next few years!
