Scientists have found a new moon hidden in one of Saturn's dazzling outer rings. The international Cassini spacecraft spotted the moon, which measures about a third of a mile wide. picked by suebe 9 months ago

Slushy geysers on Saturn's moon Enceladus erupt from fractures clustered around a hot spot at the satellite's south pole, scientists have now confirmed. Using NASA's Cassini spacecraft, researchers recorded the location of jet events on Enceladus for two years. picked by AutumnLotus 2 years ago

An enormous plume of dust and water spurts violently into space from the south pole of Enceladus, Saturn's sixth-largest moon. This raging eruption has intrigued scientists ever since the Cassini spacecraft provided dramatic images of the phenomenon. picked by AutumnLotus 2 years ago

New observations by a spacecraft suggest Saturn's second-largest moon may be surrounded by rings. If confirmed, it would the first time a ring system has been found around a moon. picked by AutumnLotus 2 years ago

By analyzing images from NASA's Cassini Radar instrument, a Brigham Young University professor helped discover and analyze mountains on Saturn's largest moon, additional evidence that it has some of the most earthlike processes of any celestial body in the solar system. picked by AutumnLotus 2 years ago

The scientists behind the Cassini orbiter have announced the discovery of Saturn's 60th moon, a little thing that showed up in time-lapse photography of the ringed planet. picked by AutumnLotus 2 years ago

Pictures from NASA sent back by the Cassini spacecraft as it passed Saturn and its moons. Cassini has been functioning in space for almost five years now, and the pictures are awesome! picked by bingo 7 months ago

NASA's Interstellar Boundary Explorer (IBEX) spacecraft has made the first observations of very fast hydrogen atoms coming from the moon, following decades of speculation and searching for their existence. picked by AutumnLotus 5 months ago

Enceladus, the tiny satellite of Saturn, is colder than ice, but data gathered by the Cassini-Huygens Mission to Saturn and Titan has detected a hot spot that could mean there is life in the old moon after all. In fact, for researchers of the outer planets, Enceladus is so intellectually hot, it's smokin'. picked by AutumnLotus 2 years ago

NASA's Cassini has been orbiting Saturn for over 4 years now, and has provided some amazing views of tiny Enceladus, some collected here. picked by MissWinkle 1 year ago

Newly assembled radar images from Cassini provide the best views of the hydrocarbon lakes and seas on Saturn's moon Titan. A new radar image reveals that Titan’s south polar region also has lakes. picked by AutumnLotus 2 years ago

This 113 mile-diameter, potato-shaped moon of Saturn is covered with craters. It shares an orbit with another moon--Epimetheus, and the two moons trade positions every four years. picked by Fanatic 3 years ago

The groundbreaking discovery was made after analysis of instruments on the US-European Cassini probe, the spacecraft that has been orbiting Saturn since 2004 following a 3.5 billion-kilometer (2.2 billion miles) voyage. picked by AfroMosHi 1 year ago

Cassini scientists may have identified the source of one of Saturn's more mysterious rings. Saturn's G ring likely is produced by relatively large, icy particles that reside within a bright arc on the ring's inner edge. picked by AutumnLotus 2 years ago

In the first video showing the auroras above the northern latitudes of Saturn, Cassini has spotted the tallest known "northern lights" in the solar system, flickering in shape and brightness high above the ringed planet. picked by AutumnLotus 2 days ago

Earthlings have mapped the moon's surface for the past 4,000 years, but NASA's latest view is the best yet.

Scientists have created a new map of the south lunar pole with Earth-based telescopes that is 50 times more detailed than the last version, created with data from the Clementine spacecraft in 1994. picked by AutumnLotus 2 years ago

Newly reprocessed images of the Moon's far side taken by Soviet spacecraft more than 40 years ago may have confirmed that the Moon's biggest impact scar was glimpsed far earlier than previously thought. picked by AutumnLotus 3 years ago

Sir Bernard Lovell, the astronomer, was among the team listening to transmissions coming from the area of space and began tracking the unmanned Soviet spacecraft Luna 15, which was trying to collect samples of lunar soil and rock and then return to Earth before the US mission. picked by kakana 5 months ago

Astronomers have found the strongest evidence yet for an ocean beneath the icy shell of Saturn's Enceladus, suggesting it could join the exclusive club of watery moons in our solar system. picked by AutumnLotus 5 months ago

Thursday, May 31 brings us the second of two full Moons for North Americans this month. Some almanacs and calendars assert that when two full Moons occur within a calendar month, that the second full Moon is called the "Blue Moon." picked by AutumnLotus 3 years ago
