Some astronomers found signs of great plumes of water erupting from the surface of Europa, one of the larger moons of Jupiter — and water could mean life, which has everyone jumping around in excitement. The best bit? They found the evidence buried deep in archived data from a 20-year-old space mission. See, *that's* why you don't just throw away old files — you never know what you'll find!
