🌌 Signs of Life Beyond Earth? Scientists Detect Potential Biosignatures on Distant Exoplanet

For decades, the question “Are we alone in the universe?” has lingered at the edge of human curiosity. In April 2025, that question took a dramatic leap toward an answer. Astronomers analyzing data from the James Webb Space Telescope (JWST) have detected potential signs of life on an exoplanet called K2-18b , located about 124 light-years away in the constellation Leo. This marks one of the most compelling discoveries in the search for extraterrestrial life — and the implications are staggering. 🪐 What is K2-18b? K2-18b is no ordinary exoplanet. It's what scientists call a "Hycean" planet — a type of exoplanet with a hydrogen-rich atmosphere and a potentially water-covered surface. It’s over twice the size of Earth and orbits within the habitable zone of its star, meaning it’s at just the right distance to support liquid water — a key ingredient for life as we know it. 🔬 The Discovery: Dimethyl Sulfide (DMS) Using the JWST's powerful instruments, researchers d...
