Scientists detect potential signs of life on exoplanet K2-18b, but more confirmation is needed.

Scientists using the James Webb Space Telescope detected potential biosignatures, including gases produced by marine microbes on Earth, in the atmosphere of exoplanet K2-18b. Located 124 light-years away, K2-18b is in a zone where conditions could support liquid water. While the findings are promising, other astronomers call for further confirmation, as the detection of these gases needs to be verified with additional telescope observations.
