Saturn Storm Aftermath Seen By Cassini
2012-10-25 12:54:42

[ Watch the Video: Saturn´s Record-Setting Storm ] Lee Rannals for redOrbit.com - Your Universe Online As the "Perfect Storm" begins to set its place on the East Coast, there has been another massive storm that has taken place, but not on this planet. NASA's Cassini spacecraft tracked the aftermath of a rare massive storm on Saturn, revealing disturbances in the planet's upper atmosphere long after the visible signs of the storm abated. Data from Cassini's composite infrared...

Strange Weather Patterns On Uranus
2012-10-21 08:59:09

April Flowers for redOrbit.com — Your Universe Online New, exquisitely detailed, high-resolution images of Uranus show off its complex weather patterns and new features of the planet that scientists can't explain yet. Uranus, the seventh planet from the Sun, is an ice giant composed mainly of frozen methane, water, ammonia and hydrocarbons. In 1986, Voyager 2 passed by Uranus and returned the iconic image that most associate with the planet. This image showed a smooth, blue-green...

Giant Impacts Formed The Moons Of Saturn
2012-10-17 14:58:59

Lee Rannals for redOrbit.com — Your Universe Online Planetary scientists claim in a paper published in Icarus that Saturn's moons may have formed due to giant impacts. Erik Asphaug, professor of Earth and Planetary Sciences at the University of California, Santa Cruz (UCSC), presented the new model at the annual meeting of the Division for Planetary Sciences of the American Astronomical Society (AAS). Asphaug and co-author Andreas Reufer of the University of Bern found that...

Saturn Moon Titan Is Baking Up Something Strange
2012-10-17 09:16:39

April Flowers for redOrbit.com - Your Universe Online What resembles a giant hot cross bun? According to radar images from NASA's Cassini spacecraft, a mysterious, nearly circular feature on Saturn's moon Titan does. The report, given at the American Astronomical Society's Division of Planetary Sciences conference suggests that there is also evidence of ancient shorelines. When you bake bread, sometimes the steam causes the top of the bread to lift and crack. The research team believes...

Cassini Going Strong 15 Years After Launch
2012-10-16 09:04:52

Brett Smith for redOrbit.com - Your Universe Online As the Cassini spacecraft hurtles around Saturn along its continuing mission, NASA announced the fifteen-year anniversary of the probe´s launch this week. The $3.3-billion mission lifted off the launch pad on October 15, 1997 and has traveled over 3.8 billion miles since – flying past Venus twice and Jupiter once en route to entering orbit around the ringed planet in 2004. The mission has provided a treasure trove of...

Titan Seasons Documented
2012-09-28 21:57:08

Lee Rannals for redOrbit.com — Your Universe Online As the fall season starts to ramp up here in the U.S., observations show Saturn's moon Titan has its own drastic seasonal changes. Astronomers presented findings at the European Planetary Science Congress on Friday about Titan's seasonal changes for the past 30 years. “As with Earth, conditions on Titan change with its seasons," Dr. Athena Coustenis from the Paris-Meudon Observatory in France, who analyzed the data, said...

Moon Of Saturn May Be Next Big Space Mission
2012-09-28 14:41:47

April Flowers for redOrbit.com - Your Universe Online We have sent a man to the moon, rovers to Mars and two Voyager missions into the great unknown reaches of space. Perhaps, it's time to land a boat on Titan. Although this idea is just in the concept stage, scientists say it is time to really consider it, and a group of engineers presented their proposals at the European Planetary Science Congress (EPSC) on September 27, 2012. The European Planetary Science Congress (EPSC) is an...

Mimas Disturbs Saturn's B-ring
2012-09-11 05:20:55

April Flowers for redOrbit.com - Your Universe Online 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. Saturn's B-ring is the largest and brightest of the gas giant's rings, the outer portion of which can be seen on the left side of the image. The moon, Mimas, which orbits Saturn once during every...

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...
