Latest Rings of Saturn Stories
A new NASA study introduces a cautionary note in the interpretation of rings and spiral arms as signposts for new planets. The team discovered interactions between gas and dust may cause a debris disk, under the right circumstances, to produce narrow rings on its own without a planet present.
The jointly operated NASA/ESA/ASI Cassini-Huygens orbiter exploring Saturn is set to take a spectacular image of Earth this afternoon – July 19 – during a solar eclipse of the sixth planet. Earth will actually appear as a small, pale blue dot between the rings of Saturn during the mosaic imaging event.
For the first time, scientists get a look at a meteoroid crashing through Saturn's rings thanks to imaging by the Cassini spacecraft that is in orbit around the sixth planet from the Sun.
The European Space Agency (ESA) released an image of Saturn's rings on Monday provided by NASA's Cassini spacecraft. Clumpy particles in the B-ring are in stark contrast to the delicately ordered ringlets of the rest of Saturn's rings.
Scientists studying images from NASA’s Cassini spacecraft have found evidence of massive snowballs dragging glittering trails from one of Saturn’s rings.
A team of astrophysicists from the University of Rochester and Europe has discovered a ring system in the constellation Centaurus that invites comparisons to Saturn.
Scientists have uncovered how nature minimizes energy costs in rings of liquids with an internal nanostructure made of two chemically discordant polymers joined with strong bonds, or di-blocks, deposited on a silicon surface.
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;...
