Our neighboring planet appears bright in the morning twilight of the ALMA radio telescopes, situated at 5,000 meters (16,000 ft) in the Chilean Andes. Groundbreaking observations, using this array of 66 dishes and the JCMT telescope in Hawaii, revealed a possible sign of life in the clouds over Venus. The hottest solar system planet, with a surface temperature of 465°C (900°F), along with a crushing atmospheric pressure of 93 bar doesn't sounds a good place for life, but scientists speculated for decades that Venus's atmosphere could be home to aerial microbes. Now a rare molecule known as phosphine was observed in Venus's clouds. On Earth it is produced by microbes in oxygen-free environments. Sample return missions are needed to confirm this, but it's certainly an exciting time for astronomy and space exploration.
