Cassini Records Possible Supernova Shockwave On Saturn
2013-02-18 16:08:11

Lee Rannals for redOrbit.com - Your Universe Online For the first time, scientists from the international Cassini spacecraft have detected subatomic particles that have been accelerated to ultra-high energies in a blast of solar wind around Saturn, hinting at the possibility that the ringed planet may have experienced the aftermath of a supernova. According to a report by the European Space Agency (ESA) that appeared recently in the journal Nature Physics, this acceleration may be the...

Smog Detected At Northern Hemisphere Of Saturn Moon Titan
2013-02-05 08:33:50

April Flowers for redOrbit.com - Your Universe Online An international group of scientists, led by Panayotis Lavvas of the University of Reims, Champagne-Ardenne, used data from NASA's Cassini mission to describe, in unparalleled detail, how aerosols in the highest part of the atmosphere are kick-started on Saturn's moon Titan. The study, published in a recent issue of Proceedings of the National Academy of Sciences (PNAS), seeks to understand aerosol formation at Titan because it could...

Six Month Saturn Storm Eats Itself
2013-01-31 19:48:37

Lee Rannals for redOrbit.com — Your Universe Online Cassini mission scientists have observed a huge thunder-and-lightning storm on Saturn consume itself for the first time. The NASA scientists said in a paper published in the journal Icarus that they observed as the massive storm made its way around the planet, until it ran into its own tail and dissipated. "This Saturn storm behaved like a terrestrial hurricane - but with a twist unique to Saturn," Andrew Ingersoll, a Cassini...

NASA Engineers Test Fire 1960s-Era Apollo Engine For Future Rocket Design
2013-01-25 08:57:01

[Watch Video: F-1 Engine Gas Generator Testing] Lawrence LeBlond for redOrbit.com - Your Universe Online Sometimes moving forward requires a little looking back. And at NASA, looking back to the days of the Apollo program is helping space engineers develop the next generation of rockets for the future of space travel. NASA resurrected the mighty F-1, an engine that powered the Saturn V rocket, to help engineers develop a heavy lift rocket for missions to the moon and beyond. The NASA...

Lack Of Craters On Titan Makes Moon Look Younger
2013-01-17 15:10:00

Lee Rannals for redOrbit.com — Your Universe Online New research based on observations from NASA's Cassini spacecraft show that Titan, Saturn's largest moon, may look younger than it really is. While most moons display their age through their thousands of craters, NASA said that Titan's craters are being erased, giving it a 'Benjamin Button' appearance. "Most of the Saturnian satellites - Titan's siblings - have thousands and thousands of craters on their surface. So far on...

Huygens Celebrates Eighth Year Since Titan Landing
2013-01-14 10:43:09

[ Watch the Video: The Huygens Experience ] Lee Rannals for redOrbit.com - Your Universe Online Eight years ago today, Huygens became the first probe to touch down on the surface of Saturn's moon Titan. Huygens was first released from the international Cassini spacecraft on Christmas Day 2004, and it arrived at Titan three weeks later. Cassini has been orbiting around Saturn since July 2004, and the spacecraft will continue its operations until 2017. ESA released an animation...

New Cassini Images Indicate Floating Ice On Titan
2013-01-09 09:16:27

April Flowers for redOrbit.com - Your Universe Online Scientists at NASA's Cassini mission revealed today that blocks of hydrocarbon ice might cover the surface of existing lakes and seas of liquid hydrocarbon on Saturn's moon Titan. Cassini's mixed readings from the reflectivity of the surfaces of the lakes on Titan might be explained by the presence of ice floes. "One of the most intriguing questions about these lakes and seas is whether they might host an exotic form of life," said...

Transit Of Venus Across The Sun Occurs Today
2012-12-21 07:49:58

Lawrence LeBlond for redOrbit.com - Your Universe Online So it´s December 21st and the world is still here. Does that mean the doomsayers were full of baloney? Or did they just misread the warnings? Perhaps the Mayans knew today´s date was special for some other reason than total annihilation. If so, then you may be happy to know they would have been right. Phil Nicholson, a Cornell University scientist said this week that Venus will be making a second transit across the face...

Cassini Captures Stunning Images Of Saturn
2012-12-19 09:59:40

April Flowers for redOrbit.com - Your Universe Online Delivered just in time for the holiday season, another glorious, backlit image of the planet Saturn has arrived from NASA's Cassini spacecraft, which has been in orbit around the planet for more than eight years. Cassini was deliberately positioned within Saturn's shadow during its 174th orbit around the gas giant on October 17, 2012. This positioning made for a perfect location from which to look in the direction of the Sun and...

Cassini Spots Nile River On Saturn's Moon Titan
2012-12-13 05:33:28

Lee Rannals for redOrbit.com - Your Universe Online The Cassini mission has spotted a miniature extraterrestrial version of the Nile River on Saturn's moon Titan. The find is the first time images have revealed a tier system this vast, and in such high resolution at any place other than Earth. Scientists believe the river is filled with liquid because it appears dark along its entire extend in the images. “Though there are some short, local meanders, the relative...

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...
