Preston Dyches, NASA Jet Propulsion Laboratory and Seth Shostak, SETI Institute 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. And so it is with the ever-changing rings of Saturn. Case in point: Saturn's narrow, chaotic...

redOrbit Staff & Wire Reports - Your Universe Online [ Watch the Video: Cassini Saturn Arrival ] Monday, 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. Cassini reached its destination on June 30, 2004, carrying with it the European Space...

Cassini Eyes Possible New Moon Forming In Saturn's Orbit
2014-04-15 08:45:46

Brett Smith for redOrbit.com - Your Universe Online Newly released images from NASA’s Cassini probe have revealed the “birthing” of a tiny moon in orbit around Saturn. The images, taken exactly one year ago on Tuesday, showed evidence of the formation of a tiny icy moon, named “Peggy” – according to a new report on the find in the journal Icarus. The study authors said the discovery could provide information about the formation of Saturn’s other moons as well as the...

WASHINGTON, April 14, 2014 /PRNewswire-USNewswire/ -- NASA's Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn that may be a new moon, and may also provide clues to the formation of the planet's known moons. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Images taken with Cassini's narrow angle camera on April 15, 2013 show disturbances at the very edge of Saturn's A ring -- the outermost of the planet's large, bright rings. One...

Lee Rannals for redOrbit.com - Your Universe Online NASA has released a new image taken by its Cassini spacecraft that shows off features of Saturn with Earth in the background. The new image, consisting of 141 wide-angle images, shows the view of Saturn as it would be seen by human eyes. The image sweeps 404,880 miles across Saturn and its inner ring system, showing the planet’s moons and rings, Earth, Venus and Mars. "In this one magnificent view, Cassini has delivered to us a...

Backlit Saturn Infrared Images

Brett Smith for redOrbit.com - Your Universe Online Without the sun to illuminate it, the ‘back’ of Saturn may not seem like much to look at. However, new images taken in the infrared spectrum that were released by NASA have revealed new details about the planet and its rings that are difficult to see from a sunlit view. "Looking at the Saturn system when it is backlit by the sun gives scientists a kind of inside-out view of Saturn that we don't normally see," said Matt Hedman, a...

Disk Patterns Not Always Formed In Presence Of Planets

[WATCH VIDEO: It Doesn't Take A Planet To Make A Ring] April Flowers for redOrbit.com - Your Universe Online Young stars known to host planets generally also have disks containing dust and icy grains, particles produced by collisions among asteroids and comets also orbiting the star. Often, these debris disks have sharply-defined rings or spiral patterns, which could signal the presence of orbiting planets. As a way to better understand the physical properties of known planets and...

Cassini Spacecraft To Take Picture Of Earth From Nearly 900 Million Miles Away

Lawrence LeBlond for redOrbit.com - Your Universe Online The jointly operated NASA/ESA/ASI Cassini-Huygens orbiter exploring Saturn is set to take a spectacular image of Earth on the afternoon of 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. NASA has invited the public to help acknowledge the interplanetary portrait by waving up to the skies when the image is taken....

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;...
