Cassini Nears 100th Titan Flyby
2014-03-06 09:16:49

NASA Ten years ago, we knew Titan as a fuzzy orange ball about the size of Mercury. We knew it had a nitrogen atmosphere -- the only known world with a thick nitrogen atmosphere besides Earth. But what might lie beneath the hazy air was still just a guess. On March 6, NASA’s Cassini spacecraft will swoop down within 933 miles (1,500 kilometers) of Titan to conduct its 100th flyby of the Saturn moon. Each flyby gives us a little more knowledge of Titan and its striking similarities to...

Saturn And Moons Show Off For The Holidays
2013-12-24 04:10:50

redOrbit Staff & Wire Reports - Your Universe Online Just in time for the holiday season, NASA’s Cassini spacecraft has captured new images of Saturn and two of its moons – including Enceladus, a “white, glittering snowball of a moon,” the US space agency announced on Monday. Featured in the collection of newly-released images (which can be viewed online) are two views of Enceladus that highlight the several ridges and features that highlight the surface of the icy moon. The...

Saturn And Earth Pose Together In New Cassini Image
2013-11-12 11:30:14

Lee Rannals for redOrbit.com - Your Universe Online NASA has released a new image taken by its Cassini spacecraft that shows off features of Saturn with Earth in the background. The new image, consisting of 141 wide-angle images, shows the view of Saturn as it would be seen by human eyes. The image sweeps 404,880 miles across Saturn and its inner ring system, showing the planet’s moons and rings, Earth, Venus and Mars. "In this one magnificent view, Cassini has delivered to us a...

Titan's Land Of Lakes
2013-10-24 04:25:21

April Flowers for redOrbit.com - Your Universe Online The sun is now shining down over the northern pole of Saturn's moon, Titan. Combine that with a bit of lucky weather and trajectories that put the spacecraft into optimal viewing positions, and NASA's Cassini spacecraft has obtained new pictures of the liquid methane and ethane lakes and seas near the moon's north pole. New clues about the formation of the lakes, and the Earth-like "hydrologic" cycle, which involves hydrocarbons rather...

Was Life On Earth Jump-Started By Icy Comet Impact?
2013-09-16 07:00:57

[ Watch the Video: Comets May Have Provided Earth The Building Blocks Of Life ] Lawrence LeBlond for redOrbit.com - Your Universe Online An international group of scientists has discovered that life on Earth may have been jump-started when icy comets bombarded the planet billions of years ago. Scientists from University College London, the University of Kent and Lawrence Livermore National Laboratory have published a paper, appearing on the Nature Geosciences website on September 15....

Cassini Data Reveals Unexpected Features In Titan’s Icy Outer Shell
2013-08-28 15:52:50

[ Watch the Video: A Titan View from Huygens ] Lee Rannals for redOrbit.com - Your Universe Online Cassini, a joint NASA/ESA/ASI orbiter, arrived at Saturn a little over nine years and has been observing the ringed planet and its moons ever since. The latest data from the spacecraft shows that the planet's largest moon, Titan, has some unexpected features. A new study published in the journal Nature reveals that Titan's rigid outer ice shell has some features quite different from any...

NASA Releases "Wave At Saturn" Collage From Cassini Photo Shoot
2013-08-21 14:42:30

Lee Rannals for redOrbit.com - Your Universe Online NASA released a collage assembled from images taken on July 19, 2013 as part of the "Wave at Saturn" event organized by the space agency's Cassini mission. In July, the Cassini spacecraft snapped an image of Earth from 900 million miles away as part of a larger set of images it was collecting of the Saturn system it is orbiting. NASA let the public know that its spacecraft would be taking the image, and started an event asking the...

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:

out-herod
  • In the phrase to out-herod Herod, to be more violent than Herod (as represented in the old mystery plays); hence, to exceed in any excess of evil.
Herod refers to 'Herod the Great,' a Roman client king and 'a madman who murdered his own family and a great many rabbis.' According to the OED, the term is 'chiefly with allusion to Shakespeare's use' in Hamlet.
