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.
A powerful lightning storm in Saturnâ€™s atmosphere that began in mid-January 2009 has become the Solar Systemâ€™s longest continuously observed thunderstorm.
PASADENA, Calif., June 24 /PRNewswire-USNewswire/ -- For the first time, scientists working on NASA's Cassini mission have detected sodium salts in ice grains of Saturn's outermost ring.
A team of planetary scientists working on the NASA/ESA/ASI Cassini-Huygens mission has discovered tiny, charged icy particles in the plume from Saturnâ€™s moon Enceladus that offer a tantalizing glimpse of the interior of this enigmatic world.
On February 24, 2009, the NASA/ESA Hubble Space Telescope captured a photo sequence of four moons of Saturn passing in front of their parent planet.
NASA's Cassini spacecraft has found within Saturn's G ring an embedded moonlet that appears as a faint, moving pinprick of light.
Supercomputer simulations of dusty disks around sunlike stars show that planets nearly as small as Mars can create patterns that future telescopes may be able to detect. The research points to a new avenue in the search for habitable planets.
NASA's Cassini spacecraft has detected a faint, partial ring orbiting with one small moon of Saturn, and has confirmed the presence of another partial ring orbiting with a second moon.
A team of scientists led from the UK has discovered that the rapid changes in Saturn's F ring can be attributed to small moonlets causing perturbations.
Planetary Ring -- A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but all four of the solar system's gas giant planets (Jupiter, Saturn, Uranus, Neptune) possess ring systems of their own. The origin of planetary rings is not precisely known, but they are thought to be unstable and dissipate over the course of tens or hundreds of millions of...
Saturn's moon Prometheus -- Prometheus [pra-MEE-thee-us] is the third of Saturn's known satellites. It was discovered from photographs taken by Voyager during its encounter with Saturn by S. Collins and others. Prometheus acts as a shepherd satellite for the inner edge of Saturn's F Ring. The moon is extremely elongated about 145 by 85 by 62 kilometers (90 by 53 by 39 miles) in diameter. It has a number of ridges and valleys on its northern side. Several craters about 20...
Saturn's moon Pan -- Pan, the innermost known satellite, was found from photographs taken by Voyager during its encounter with Saturn. It was discovered by Mark R. Showalter in 1990, 9 years after the Voyager encounter. Pan is located 133,583 kilometers from the center of Saturn and is within the Encke Gap of Saturn's A-ring. It acts as a shepherd and is responsible for keeping the Encke gap open. It has a diameter of 20 kilometers. ----- Discovered by: Mark R. Showalter;...
