    Using data from the James Webb Space Telescope (JWST), the astronomers, led by the University of Cambridge, have identified the chemical fingerprints dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) – molecules that indicate life. Here on Earth, these molecules are only produced by living organisms – primarily microbial life such as marine phytoplankton. The molecules have been detected in the atmosphere of exoplanet K2-18b, which is located around 124 light-years from Earth in the constellation of Leo.

    This artist’s concept shows what exoplanet K2-18 b could look like based on science data. K2-18 b, an exoplanet 8.6 times as massive as Earth, orbits the cool dwarf star K2-18 in the habitable zone and lies 120 light-years from Earth. A new investigation with NASA’s James Webb Space Telescope into K2-18 b has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. The abundance of methane and carbon dioxide, and shortage of ammonia, support the hypothesis that there may be a water ocean underneath a hydrogen-rich atmosphere in K2-18 b.

    Exoplanet K2-18 b lies in the habitable zone of its host star some 110 light-years from Earth. In a major first, scientists have detected water vapor and possibly even liquid water clouds that rain in the atmosphere of a strange exoplanet that lies in the habitable zone of its host star about 110 light-years from Earth. A new study focuses on K2-18 b, an exoplanet discovered in 2015, orbits a red dwarf star close enough to receive about the same amount of radiation from its star as Earth does from our sun. Previously, scientists have discovered gas giants that have...
