Scientists have discovered phosphine gas in the atmosphere of Venus, indicating the possibility of extraterrestrial life on the planet. The gas, typically released by living organisms, has been found at a depth deeper than previously observed. The discovery was made by a team of scientists from Cardiff University, who focused on studying the top and middle clouds in the planet's atmosphere using the James Clark Maxwell Telescope. While some argue that the presence of phosphine is insufficient to confirm life, this breakthrough marks a significant milestone in the quest for extraterrestrial life.
