An illustration based on scientific evidence showing what exoplanet K2-18b might look like.A distant world unlike any planet in our own Solar System could potentially be “teeming” with life, according to a groundbreaking new study.  “We found the strongest evidence to date of possible biological activity on an exoplanet,” University of Cambridge Professor Nikku Madhusudhan said in a video announcement. Madhusudhan and his team used data from the James Webb Space Telescope to find chemical signatures they believe suggest life on K2-18b.That’s a planet about two and a half times the size of Earth, and 8.6 times more massive, that sits in the habitable “Goldilocks Zone” of a dwarf star about 120 light years away.They looked specifically for something called DMS, or dimethyl sulfide, a chemical that on Earth is produced solely by living organisms such as algae.It’s so uniquely produced by life that scientists have theorized that checking other planets for its “biosignature” could be the key to finding life outside of our own planet. And that’s what they’ve found, as well as another potential marker of life called DMDS, and in levels thousands of times higher than what’s seen
