Preliminary data from NASA’s James Webb Space Telescope (JWST) suggests a more than 50% likelihood of dimethyl sulfide (DMS) gas on the exoplanet K2-18b. However, further analysis is required before a definitive conclusion can be reached. DMS is a gas that is only produced by living beings on Earth, primarily by phytoplankton in marine environments. The presence of DMS in K2-18b’s atmosphere could be a groundbreaking discovery, as the planet is believed to be ocean-covered and 2.6 times larger than Earth. K2-18b, discovered in 2015, is a super Earth exoplanet orbiting an M-type star. M stars, smaller and cooler than the sun, comprise the Red Dwarf category. K2-18b resides in the Goldilocks zone, where temperatures sustain liquid water.
