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 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 Data Indicates Saturn’s Moon Titan Is Icier Than Thought
2012-12-04 08:44:39

Lawrence LeBlond for redOrbit.com - Your Universe Online Titan, Saturn´s largest moon, has long been projected as an icy body with a vast ocean of liquid water underneath its crust. A recent analysis suggested that heat generated from within the natural satellite helps keep this ocean from freezing due to interactions it has with Saturn and the other moons. And now, a new analysis of the moon´s topography and gravity indicates that its icy outer crust is twice as dense as...

Titan Sees Seasonal Changes
2012-11-28 21:47:01

Peter Suciu for redOrbit.com — Your Universe Online To every thing there is a season, and a time to every purpose under the heaven. While the Book of Ecclesiastes and American folk singer Pete Seeger may not have considered Titan, the planet Saturn´s largest moon, as something unto which there is a season, it does seem that the moon has seen a type of turn or change in the seasons. On Wednesday, scientists using the international Cassini spacecraft have studied the rapid...

Pac-Man Seen Near Saturnpacman
2012-11-26 21:52:11

Lee Rannals for redOrbit.com — Your Universe Online NASA announced on Monday its Cassini spacecraft has helped to discover a "video gamers' paradise" at Saturn. The space agency said scientists have spotted a second feature shaped like the 1980s video game icon Pac Man in the Saturn system on the moon Tethys. The pattern found appears in the thermal data obtained by Cassini composite infrared spectrometer. "Finding a second Pac-Man in the Saturn system tells us that the...

Cassini Shows Titan Glow In The Dark On Halloween
2012-11-01 06:21:22

NASA/Jet Propulsion Laboratory A literal shot in the dark by imaging cameras on NASA's Cassini spacecraft has yielded an image of a visible glow from Titan, emanating not just from the top of Titan's atmosphere, but also - surprisingly - from deep in the atmosphere through the moon's haze. A person in a balloon in Titan's haze layer wouldn't see the glow because it's too faint - something like a millionth of a watt. Scientists were able to detect it with Cassini because the spacecraft's...

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...

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...

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:

  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
