One hundred and one geysers discovered on Saturn's moon Enceladus

NASA’s spacecraft Cassini has mapped 101 geysers erupting from a row of fractures in the ice shell of Enceladus, one of Saturn’s moons, researchers reported this week. Cassini surveyed Enceladus’s four “tiger stripe” fractures for years, using heat-sensing instruments to collect data on the area. Using these data, the scientists pinpointed hot spots coinciding with the geysers. The hot spots were too small to have come from friction generated by the fractures’ walls rubbing together, so the scientists concluded that the geysers must burst through from the sea trapped beneath Enceladus’s ice shell.
