dancing auroral lights on Saturn
2014-05-19 11:09:00

University of Leicester University of Leicester researchers have captured stunning images of Saturn's auroras as the planet's magnetic field is battered by charged particles from the Sun. The team's findings provide a "smoking gun" for the theory that Saturn's auroral displays are often caused by the dramatic collapse of its "magnetic tail". [ Watch the Video: Dance of Saturn’s Auroras ] Just like comets, planets such as Saturn and the Earth have a "tail" – known as the...

What Would Happen If Saturn Came Extremely Close To Earth?

redOrbit Staff & Wire Reports - Your Universe Online While astronomers enjoyed the best view of Saturn this past weekend, an animator created a new video depicting what would happen if the people of Earth got an extreme close-up of the sixth planet from the Sun. According to Laurel Kornfeld of The Space Reporter, Saturn reached opposition on May 10, which means that it and the Earth were on opposite sides of the Sun. The ringed planet was also at its closest distance to our world...

Saturn's Hexagon: An amazing Phenomenon

Universidad del País Vasco Researchers of the University of the Basque Country reveal some of the secrets of Saturn's mysterious hexagonal wave, including its rotation period, which could be that of the planet itself In 1980 and 1981 NASA's Voyager 1 and 2 space probes passed for the first time over the planet Saturn, located 1,500 million km from the Sun. Among their numerous discoveries they observed a strange, hexagon-shaped structure in the planet's uppermost clouds surrounding its...

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...

[ Watch the Video: Artist’s Impression of Ring System Around Chariklo ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers writing in the journal Nature say they have observed a minor planet which contains two rings of ice and pebbles for the first time. Chariklo sits about 1.2 billion miles out in the solar system between Saturn and Uranus, and the minor planet, or asteroid, has been known about for many years. However, this is the first time astronomers discovered...

Saturn And Earth Pose Together In New Cassini Image

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...

Cassini Uncovers New Data About Saturn's Atmosphere Composition

[ Watch the Video: Saturn Storm Reveals Its Explosive Power ] Lee Rannals for redOrbit.com - Your Universe Online A new analysis of near-infrared images taken by NASA's Cassini orbiter is providing more data about the composition of Saturn's atmosphere. Scientists, publishing a paper in the journal Icarus, say they have discovered that cloud particles at the top of Saturn's great storms are composed of a mix of three substances, including water ice, ammonia ice and an uncertain third...

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...

Planet Neptune -- Neptune is the eighth planet from the sun. It is a gas giant. Orbiting so far from the sun, Neptune receives very little heat. Its 'surface' temperature is -218 degrees Celsius (below zero). However, the planet seems to have an internal source of heat. It is thought that this may be leftover heat generated by infalling matter during the planet's birth, now slowly radiating away into space. Neptune's atmosphere has the highest wind speeds in the solar system, up to...

The Planet Saturn -- in astronomy, 6th planet from the sun. Astronomical and Physical Characteristics of Saturn Saturn's orbit lies between those of Jupiter and Uranus; its mean distance from the sun is c.886 million mi (1.43 billion km), almost twice that of Jupiter, and its period of revolution is about 291/2 years. Saturn appears in the sky as a yellow, starlike object of the first magnitude. When viewed through a telescope, it is seen as a golden sphere, crossed by a series of...
