Cassini Reveals New Ring Quirks, Shadows During Saturn Equinox
PASADENA, Calif. - NASA scientists are marveling over the extent of ruffles and dust clouds revealed in the rings of Saturn during the planet's equinox last month. Scientists once thought the rings were almost completely flat, but new images reveal the heights of some newly discovered bumps in the rings are as high as the Rocky Mountains. NASA released the images last week.
Salt Finding from NASA's Cassini Hints at Ocean within Saturn Moon
PASADENA, Calif. - For the first time, scientists working on NASA's Cassini mission have detected sodium salts in ice grains of Saturn's outermost ring. Detecting salty ice indicates that Saturn's moon Enceladus, which primarily replenishes the ring with material from discharging jets, could harbor a reservoir of liquid water - perhaps an ocean - beneath its surface.
Saturn's Dynamic Moon Enceladus Shows More Signs of Activity
SAN FRANCISCO - The closer scientists look at Saturn's small moon Enceladus, the more they find evidence of an active world. The most recent flybys of Enceladus made by NASA's Cassini spacecraft have provided new signs of ongoing changes on and around the moon. The latest high-resolution images of Enceladus show signs that the south polar surface changes over time.
NASA Confirms Liquid Lake On Saturn Moon
PASADENA, Calif. - NASA scientists have concluded that at least one of the large lakes observed on Saturn's moon Titan contains liquid hydrocarbons, and have positively identified the presence of ethane. This makes Titan the only body in our solar system beyond Earth known to have liquid on its surface.
