Water Vapor Plumes on Europa

Scientists have made the first direct detection of water vapor on Jupiter's moon Europa using the Keck telescope in Hawaii. This discovery, based on infrared signals, supports the theory of a subsurface ocean beneath Europa's icy crust. Observations over 17 days revealed a spike in infrared light, indicating water vapor. The detection of over 2000 tons of water vapor is significant for understanding Europa's potential to support life. This finding will guide future missions, including NASA's Europa Clipper, to further explore Europa's secrets and its potential for life beyond Earth.
