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

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...

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...

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:

callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
