Astronomers have detected the most promising 'hints' of potential life on a planet beyond our solar system, though other scientists express skepticism. The planet K2-18b, 124 light-years away in the Leo constellation, is believed to be an ocean world capable of hosting microbial life. Using the James Webb Space Telescope, researchers detected signs of two chemicals in the planet's atmosphere that are considered 'biosignatures' for extraterrestrial life. While caution is emphasized and more observations are needed, this discovery could be a significant step towards finding evidence of life beyond Earth.
