NASA's James Webb Space Telescope observes planet in a distant galaxy that might support life

NASA'S James Webb Space Telescope observed a planet outside of our galaxy that might be able to support life. Webb discovered the presence of methane and carbon dioxide on the exoplanet K2-18 b, which is 8.6 times the size of Earth. This indicates K2-18 b could be a Hycean exoplanet.

Exoplanets are planets beyond our solar system and Hycean, which comes from a combination of "hydrogen" and "ocean," describes planets that scientists hypothesize have hydrogen-rich atmospheres and liquid-water oceans, according to Space.com.

There was also a possible detection of dimethyl sulfide dimethyl sulfide, known as DMS, on K2-18 b. DMS is a molecule that, when on Earth, is produced by life, according to NASA.
