Astronomers find possible signs of alien life on massive, distance planet K2-18b. The exoplanet K2-18b is 8 times bigger than planet Earth. The claim about alien life involved data from NASA's James ...

K2-18b resides within the habitable zone of its star, making the presence of liquid water and thus life possible. Using the James Webb Space Telescope, researchers detected molecules in K2-18b's ...

K2-18b, a potentially habitable exoplanet 124 lightyears away, may contain biomarker DMS, but its habitability remains uncertain.

By comparing those fingerprints to 20 different molecules that they would potentially expect to observe in the atmosphere, ...
