K2-18B could hold the first true hint that life exists beyond Earth, After new data from the James webb space Telescope revealed signs of gases that on earth are only produced by living organisms.

šŸ”­Key Findings:

- Water vapor detected (Hubble).

- Possible Hycean worldā€”hot, ocean-covered, hydrogen-rich.

- JWST spotted methane, COā‚‚, & tentative DMS (a possible life sign).

K2-18b remains one of the most promising candidates for studying exoplanet habitability, though itā€™s likely more of a "water world" with a thick atmosphere than an Earth twin.
