Gravity Controls Enigmatic Moon's Geysers

These images from NASA’s Cassini spacecraft show how the pull of the planet affects the amount of material ejected by geysers on Saturn’s moon Enceladus. It turns out that the moon launches more spray when it is farther away from Saturn. Image Credit: NASA/JPL-Caltech/University of Arizona/Cornell/SSI

Saturn’s 314-mile-wide icy moon Enceladus has been […]
