Europa Shows Evidence Of Liquid Water
For a long time scientists have suspected the presence of liquid water under the surface of Jupiter’s moon Europa, and now Hubble is seeing water vapor from that other world. Scientists suspect that it erupted from plumes on the surface of Europa. If so, this makes it easier for future missions to investigate the chemical make-up of Europa because it means they won’t have to drill. This isn’t the first observation of water vapor on a moon. Saturn’s moon Enceladus showed signs of water vapor back in 2005. Scientists say that long fissures on Europa’s surface, known as linae, might be releasing the water vapor into space.
