Long dismissed as impossible, there is now a space race for the best possible site to find other forms of life. The Saturn moon Enceladus has taken the lead: 101 active geysers shooting water from cracks in its southern hemisphere have been discovered. That is important because water coming from deep inside the moon means there may be a reservoir of permanent liquid water there where life could thrive. The discovery came from images from NASA’s Cassini space probe and was announced in two papers in the Astronomical Journal.
