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...

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 Takes Spectacular Images Of Saturn And Moon Titan
2012-08-30 09:23:11

Lawrence LeBlond for redOrbit.com - Your Universe Online As NASA´s Cassini spacecraft continues its long-term visit of the sixth planet from the sun, it is continuing to surprise scientists with stunning images of the Saturnian environment. In the latest round of images, Cassini has shown the “true colors” of Saturn, and its largest moon Titan, in a spectacular fashion. One image captures the changing hues of Saturn´s northern and southern hemispheres as they pass...

Iapetus Ice Avalanches Explain Landslides Elsewhere
2012-07-30 04:26:15

Lee Rannals for redOrbit.com - Your Universe Online Researchers from Washington University in St. Louis, Missouri have found that giant ice avalanches on Saturn's moon Iapetus could provide clues to slippage in other places in the Solar System. Kelsi Singer, graduate student in Earth and planetary sciences in Arts & Sciences at the university, says that landslides take place everywhere in the Solar System, but Iapetus has more giant landslides than any celestial body in our...

Lack Of Erosion On Titan Puzzles Scientists
2012-07-21 07:24:25

redOrbit Staff & Wire Reports - Your Universe Online By studying photographs of Saturn's moon Titan, researchers from a pair of US universities have discovered that the satellite's river networks caused little erosion in some areas, leading them to believe that either erosion there is exceptionally slow or that some other phenomenon wiped out older riverbeds and landforms. The research, which was conducted by experts from the Massachusetts Institute of Technology and the University...

Saturn Lightning Caught By Cassini
2012-07-19 07:52:38

Lawrence LeBlond for redOrbit.com - Your Universe Online NASA´s Cassini satellite, which has been visiting Saturn now for eight years, caught a rare daytime lightning strike in a massive storm that has been plaguing the northern hemisphere of the distant ringed-planet for most of 2011. The spacecraft caught the images on March 6, 2011 and marks the first time scientists have been able to detect lightning in visible wavelengths on Saturn´s illuminated surface (side facing the...

Lee Rannals for redOrbit.com - Your Universe Online NASA's Cassini spacecraft is flying high amongst the rings of Saturn for the first time in nearly two years. The spacecraft is pumping out views of Saturn's spectacular rings because it has changed the angle at which it orbits the planet, regularly passing above and below Saturn's equatorial plane. In order to change its angle, Cassini had to use the gravity of Titan to change its trajectory. Titan revolves around Saturn within a...

Cassini, Titan, Water, Saturn
2012-06-29 04:55:20

[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online Researchers using data from NASA's Cassini spacecraft have revealed that Titan has a layer of liquid water under its ice shell. During their study, they saw a large amount of squeezing and stretching as the moon orbited Saturn. They determined that if Titan were composed entirely of stiff rock, the gravitational attraction of Saturn would cause bulges, or solid "tides," 3 feet of height. Cassini reveled that...

Lagrangian Point -- In Lagrangian mechanics, a Lagrangian point (or L-point) is one of five positions in space where the gravitational fields of two bodies of substantial but differing mass combine to form a point at which a third body of negligible mass would be stationary relative to the two bodies. Bodies at the L-point will not move relative to the parent bodies if they are not perturbed by other gravitational forces. They are sometimes also referred to as libration points. The...

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...

Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...

Saturn's moon Rhea -- Rhea is the second largest moon of Saturn. It was discovered in 1672 by Giovanni Cassini. Rhea is an icy body with a density of about 1.24 gm/cm3. This low density indicates that it has a rocky core taking up less than one-third of the moon's mass with the rest composed of water-ice. Rhea's features resemble those of Dione, with dissimilar leading and trailing hemispheres, suggesting similar composition and histories. The temperature on Rhea is -174°C in direct...

Saturn's moon Helene -- Helene is a moon of Saturn, discovered by Laques and Lecacheux in 1980 from ground-based observations. It is co-oribtal with Dione and located in its leading Lagrangian point (L4) and hence is sometimes referred to as "Dione B". ----- Orbital radius: 377,400 km Diameter: 33 km (36 x 32 x 30) Mass: Unknown Orbital period: 2.7369 days Orbital inclination: 0.2 ----- NASA Learn more on this topic from eLibrary here:
