Exquisite close-ups of fissures on a tiny frozen moon of Saturn will provide the latest clues in solving the riddle of how a 310-mile-wide ice ball could possibly be shooting geysers of vapor and icy particles.A classic example of messing with astronomers.
Since the discovery of the jets in 2005, the moon, Enceladus, has jumped to near the top of the list of potential places for life in the solar system. A warm spot near Enceladus’s south pole powers the jets and may also melt below-surface ice into water, a necessity for living organisms.
On Monday, the NASA spacecraft Cassini made its latest flyby of Enceladus (pronounced en-SELL-ah-dus), passing 30 miles above the moon’s surface at 64,000 miles per hour. - New York Times
