A stunning view of Saturn from NASA's Cassini spacecraft has made Time Magazine's 2009 "Year in Pictures."
Like sugar plum fairies in "The Nutcracker," the moons of Saturn performed a celestial ballet before the eyes of NASA's Cassini spacecraft.
PASADENA, Calif., Sept. 21 /PRNewswire-USNewswire/ -- 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.
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.
The jointly owned US and European spacecraft Cassini has transmitted raw images back to Earth of the instant Saturn reached its equinox.
Scientists believe that ice volcanoes observed on Saturnâ€™s moon Enceladus may stem from a sea beneath its surface, which could support theories for the existence of extraplanetary life.
SAN FRANCISCO, Dec. 15 /PRNewswire-USNewswire/ -- 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 closer scientists look at Saturn's small moon Enceladus, the more they find evidence of an active world.
What generates Enceladus' jet plumes is a burning question in planetary science, because if liquid water is involved, Enceladus would be shown to have everything it needs, in theory, to provide a habitable environment.
In a feat of interplanetary sharpshooting, NASA's Cassini spacecraft has pinpointed precisely where the icy jets erupt from the surface of Saturn's geologically active moon Enceladus.
