Saturn's Moon Enceladus Shoots Giant Water Geysers Into Space
Saturn's ice-covered moon Enceladus blasts roughly 200 kilograms of water vapor and ice grains per second into space from fractures near its south pole.

Roughly how many kilograms of water vapor per second does Enceladus eject into space?
Silica nanoparticles form when hot water interacts with rocky minerals at hydrothermal vents.

Why / How?
Scientific Mechanism
NASA's Cassini spacecraft flew directly through these plumes and detected salts, organic molecules, and silica nanoparticles—strong evidence of hydrothermal vents on the ocean floor. This makes Enceladus one of the prime candidates for extraterrestrial life in our solar system.
