NASA JWST Detects Possible Sign of Life Video Watch time under 1 minute April 18, 2025 Image Did the James Webb Space Telescope Just Detect Signs of Life? The James Webb Space Telescope might have just taken a huge step toward answering the age-old question: Are we alone in the universe? In this video, Talia Sepersky dives into Webb’s latest observations of exoplanet K2-18b, a potential water world located 120 light-years away. Scientists have detected dimethyl sulfide (DMS)—a gas that, here on Earth, is almost exclusively produced by ocean plankton. While the detection isn’t confirmed yet, and it’s not definitive proof of life, it’s one of the strongest hints we’ve ever had from another world. The DMS signal is still faint, but stronger than a similar observation made in 2023. Could this be the first real biosignature ever spotted on another planet?
