These are the James Webb Space Telescope's most notable discoveries in 2023.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected the chemical fingerprints of dimethyl sulfide and/or dimethyl disulfide in the atmosphere of the super-Earth exoplanet K2-18b.

NASA's Webb telescope looked at the sub-Neptune exoplanet K2-18 b. It found methane, carbon dioxide, a possible ocean, and even ... maybe ... a biosignature. The post Did Webb find signs of life on exoplanet K2-18 b? first appeared on EarthSky.

New observations by the Webb Space Telescope have reignited the debate about possible life on K2-18b, a potentially habitable exoplanet 124 light-years away. The post Life on K2-18b? Exciting new results met with skepticism first appeared on EarthSky.

James Webb has once again peered into the atmosphere of an exoplanet, and this time it has identified indications that the planet could be covered in ocean.
