Jupiter’s Hot Spots Move Like A Merry-Go-Round
2013-03-15 12:25:30

Watch the video “Jupiter´s Hot Spots” Brett Smith for redOrbit.com - Your Universe Online Planetary scientists at NASA have found that a weather phenomenon also found in Earth´s atmosphere is responsible for the activity of so-called ℠hot spots´ slightly bigger than North America drifting across Jupiter´s atmosphere. Using images taken by NASA's Cassini spacecraft as it passed Jupiter en route to Saturn, scientists have determined that hot...

Last Close Flyby Of Saturnian Moon Rhea Made By Cassini
2013-03-08 08:57:45

NASA NASA's Cassini spacecraft will be swooping close to Saturn's moon Rhea on Saturday, March 9, the last close flyby of Rhea in Cassini's mission. The primary purpose will be to probe the internal structure of the moon by measuring the gravitational pull of Rhea against the spacecraft's steady radio link to NASA's Deep Space Network here on Earth. The results will help scientists understand whether the moon is homogeneous all the way through or whether it has differentiated into the...

Cassini Spies On Earth's Sister Venus From Behind Saturn's Rings
2013-03-04 13:54:02

Lee Rannals for redOrbit.com — Your Universe Online The international Cassini spacecraft, a NASA, European Space Agency (ESA) and Italian Space Agency (ASI) jointly-operated project, has taken some unique pictures of Earth's twin planet from the perspective of Saturn. The Cassini-Huygens mission launched on October 15, 1997, traveling 2.2 billion miles toward Saturn, reaching the distant ringed-planet June 30, 2004. The orbiter includes 18 sophisticated science instruments to help...

Cassini Catches Solar Wind, Helps NASA Study Particle Acceleration
2013-02-20 14:23:12

Michael Harper for redOrbit.com — Your Universe Online As it floats around the planet Saturn, the Cassini spacecraft recently got a front row seat to what NASA astronomers are calling an “unusual strong blast of solar wind.” Shortly after this “wind” blew by, Cassini began detecting particles which had been accelerated to ultra-high energies. Particles which are accelerated this much are usually found surrounding far away supernovas. This is good news for...

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...

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...
