James Webb Telescope Discovers Signs of Life on Exoplanet K2-18b
The James Webb Space Telescope has detected biosignature gases in the atmosphere of exoplanet K2-18b, the strongest evidence yet of potential life beyond Earth. Scientists are cautiously interpreting the groundbreaking findings.
James Webb telescope discovery
Detection
JWST detected dimethyl sulfide and phosphine in K2-18b's atmosphere—gases produced on Earth primarily by biological processes. The combination is difficult to explain through non-biological chemistry.
Cautious Interpretation
Scientists emphasize this is not confirmation of life. Alternative explanations are being explored. More observations are needed, and the findings require independent verification.
Significance
If confirmed, the discovery would be among the most significant in human history. K2-18b is 120 light-years away, making direct study impossible with current technology.
The James Webb Telescope detects biosignature gases on exoplanet K2-18b, hinting at potential life beyond Earth, though further verification is needed.
