Compared to the age of the solar system -- about four-and-a-half billion years -- a couple of decades are next to nothing. Some planetary locales change little over many millions of years, so for scientists who study the planets, any object that evolves on such a short interval makes for a tempting target for study.

June 30 marks the 10th anniversary of the Cassini spacecraft’s arrival in the Saturn system, beginning a four-year primary mission that was extended on three occasions and ultimately led to the collection of more than 500 GB of data and the publication of well over 3,000 scientific papers.

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.

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;...
