Researchers Shed Light On Why Saturn Looks So Young
2013-04-30 14:52:47

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online At the dawn of our Solar System the planets were very hot, as the energy from their creation lingered. But over time the planets would cool, becoming darker, only occasionally paused in this process by large impacts or radioactive decay. At least that is what we would expect. A mystery that has puzzled scientists for half a century revolves around the appearance of the planet Saturn. The second largest planet in our Solar...

Monster Storm On Saturn Captured By Cassini
2013-04-29 13:26:47

[ Watch the Video: Mysterious Hurricane at Saturn´s North Pole ] Lee Rannals for redOrbit.com - Your Universe Online NASA's Cassini spacecraft has provided an incredible view of a monster storm on Saturn with clouds moving as fast as 300 miles per hour. High-resolution pictures and video of the storm gives a unique perspective of a hurricane with an eye measuring about 1,250 miles, which is about 20 times larger than the average hurricane eye on Earth. NASA said the hurricane is...

WASHINGTON, April 29, 2013 /PRNewswire-USNewswire/ -- NASA's Cassini spacecraft has provided scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn's north pole. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) In high-resolution pictures and video, scientists see the hurricane's eye is about 1,250 miles (2,000 kilometers) wide, 20 times larger than the average hurricane eye on Earth. Thin, bright clouds at the outer edge of the...

Slooh To Broadcast Saturn Show This Weekend
2013-04-25 19:06:02

[ Watch the Video: ScienceCasts: Saturn Close Up ] Lee Rannals for redOrbit.com — Your Universe Online This weekend, stargazers should dust-off their telescopes and catch a glimpse of Saturn at its best and brightest. On Sunday, April 28th, Saturn will be making its closest approach to Earth, appearing bigger and brighter than at any other time in 2013. Astronomers refer to this event as "an opposition," because Saturn will be opposite the sun in the skies of Earth. The...

WASHINGTON, April 25, 2013 /PRNewswire-USNewswire/ -- NASA's Cassini spacecraft has provided the first direct evidence of small meteoroids breaking into streams of rubble and crashing into Saturn's rings. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO ) These observations make Saturn's rings the only location besides Earth, the moon, and Jupiter where scientists and amateur astronomers have been able to observe impacts as they occur. Studying the impact rate of meteoroids from...

Meteoroids Slam Into Saturn’s Rings
2013-04-25 15:08:34

Lee Rannals for redOrbit.com — Your Universe Online NASA said on Thursday that its Cassini spacecraft provided the first direct evidence of small meteoroids crashing into Saturn's rings. Previously, scientists had only witnessed impacts on Earth, the moon and Jupiter as they occurred. Studying the impact rate of meteorites outside the Saturnian system helps scientists understand how different planetary systems in our Solar System formed. The meteoroids that impacted Saturn are...

Cassini Mission Tracks Vanishing Methane On Saturn's Moon Titan
2013-04-16 07:20:00

Lawrence LeBlond for redOrbit.com - Your Universe Online Part of the surface of Saturn´s moon Titan has been actively tracked by NASA´s Cassini mission for the past several years. During that time, the mission has found a remarkable presence of hydrocarbon methane lakes and seas dotting the surface of the moon. But a model developed by mission leaders at the Jet Propulsion Laboratory (JPL) in Pasadena, California, suggests the supply of these methane lakes will soon come to end....

Auroras On Saturn To Be Closely Monitored
2013-04-16 04:51:56

April Flowers for redOrbit.com - Your Universe Online An international team of researchers, in collaboration with University of Leicester planetary scientists, has organized the largest ever observational campaign of Saturn's auroras. To expand our knowledge of the planet's northern lights, a host of space and ground-based telescopes will focus on the ringed gas giant for the month-long project. Scientists from the University's Department of Physics and Astronomy have worked with NASA...

Changing Seasons On Titan
2013-04-12 07:40:24

April Flowers for redOrbit.com - Your Universe Online The latest sign that the change of seasons has started a cascade of radical changes in the atmosphere on Titan is an ice cloud taking shape over the south pole. This type of cloud, made from unknown ice, has long hung over the north pole. According to observations by the composite infrared spectrometer (CIRS) on NASA's Cassini spacecraft, the northern cloud is now fading. "We associate this particular kind of ice cloud with winter...

How Charged Water Particles Affect Saturn's Atmosphere
2013-04-10 19:36:15

Lee Rannals for redOrbit.com — Your Universe Online A new study published in the journal Nature found that the "rain" of charged water particles in Saturn's atmosphere influences the composition and temperature of the planet's upper atmosphere and rings. The study, led by the University of Leicester in England, reveals that there is a significant interaction between its atmosphere and ring system. "The main effect of ring rain is that it acts to 'quench' the ionosphere of...

Cassini-Huygens Mission -- The Cassini unmanned space probe is intended to study Saturn and its moons. It was launched on October 15, 1997 and is estimated to enter Saturn's orbit on July 1, 2004. The mission is a joined NASA/ESA project. Cassini's principal objectives are to: -- determine the three-dimensional structure and dynamical behavior of the rings -- determine the composition of the satellite surfaces and the geological history of each object -- determine the nature and...

Gas Giant
2004-10-19 04:45:41

Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...

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...

Uranus -- Uranus is the seventh planet from the sun. It is a gas giant. Physical characteristics Uranus is composed primarily of rock and various ices, with only about 15% hydrogen and a little helium (in contrast to Jupiter and Saturn which are mostly hydrogen). Uranus (and Neptune) are in many ways similar to the cores of Jupiter and Saturn minus the massive liquid metallic hydrogen envelope. It appears that Uranus does not have a rocky core like Jupiter and Saturn but rather...

Saturn's moon Phoebe -- Phoebe is the outermost of Saturn's known moons. Phoebe is almost 4 times more distant from Saturn than its nearest neighbor (Iapetus). It was discovered by William Henry Pickering in 1898. Most of Saturn's moons have very bright surfaces, but Phoebe's albedo is very low (.06), as dark as lampblack. All of Saturn's moons except for Phoebe and Iapetus orbit very nearly in the plane of Saturn's equator. Phoebe's orbit is retrograde, inclined almost 175, and is...
