Scientists at the University of Cambridge may have found a hint of alien life on the distant planet K2-18b, 120 light-years away. They detected dimethyl sulfide in its atmosphere, a molecule usually produced by ocean algae on Earth. Despite the cautious optimism, researchers stress that it's only a potential sign of microbial life, and further investigation is needed. This discovery, thanks to the James Webb Space Telescope, marks a thrilling era in space exploration as we ponder the profound question: Are we alone in the universe?
