Astronomers using the James Webb Space Telescope say they have detected the “strongest evidence yet” that life exists outside our solar system. Scientists at the University of Cambridge found signs of the gases dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS) in the atmosphere of exoplanet K2-18b. On Earth, these gases are only produced by living organisms like phytoplankton, suggesting that K2-18b may also support life. Located 124 light years away, K2-18b is almost three times the size of Earth and inhabits a region in space where temperatures might allow liquid water. This has long made the exoplanet a top candidate…
