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...

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...

Saturn’s Jet Stream Process Revealed By Cassini
2012-06-26 04:35:48

Lee Rannals for redOrbit.com NASA's Cassini spacecraft has revealed just how Saturn's jet streams work, according to a new study published in the journal Icarus. Scientists have been trying to understand the mechanism that drives Saturn's jet streams, which blow faster in other places, and churn east and west across the planet. The jet streams in Saturn's atmosphere slice across the face of the planet and are visible to the human eye, and also visible at altitudes detectable by...

The Cassini spacecraft has captured new images and measurements of some of Saturn´s moons. This new evidence may help scientists determine if life does exist outside of Earth´s closed system. Enceladus, the moon with the most promise for microbial life, has cryovolcanic geysers on its surface that spews into the moons thin atmosphere. The Cassini spacecraft flew into these plumes at an altitude of 46 miles above the surface. They used the ion and neutral mass spectrometer...

Cassini Delivers Holiday Treats From Saturn
2011-12-23 04:20:54

No team of reindeer, but radio signals flying clear across the solar system from NASA's Cassini spacecraft have delivered a holiday package of glorious images. The pictures, from Cassini's imaging team, show Saturn's largest, most colorful ornament, Titan, and other icy baubles in orbit around this splendid planet. The release includes images of satellite conjunctions in which one moon passes in front of or behind another. Cassini scientists regularly make these observations to study the...

Cassini Chronicles Life Of Saturn's Giant Storm
2011-11-18 04:09:47

New images and animated movies from NASA's Cassini spacecraft chronicle the birth and evolution of the colossal storm that ravaged the northern face of Saturn for nearly a year. These new full-color mosaics and animations show the storm from its emergence as a tiny spot in a single image almost one year ago, on Dec. 5, 2010, through its subsequent growth into a storm so large it completely encircled the planet by late January 2011. The monster tempest, which extended north-south...

This is the first time scientists have obtained current evidence of rain soaking Titan's surface at low latitudes. As spring continues to unfold on Saturn, April showers on the planet's largest moon, Titan, have brought methane rain to its equatorial deserts, as revealed in images captured by NASA's Cassini spacecraft. This is the first time scientists have obtained current evidence of rain soaking Titan's surface at low latitudes. The observations are released today in the journal Science....

Scientists believe they finally understand why one of the most dynamic regions in Saturn's rings has such an irregular and varying shape, thanks to images captured by NASA's Cassini spacecraft. And the answer, published online November 1 in the Astronomical Journal, is this: The rings are behaving like a miniature version of our own Milky Way galaxy. This new insight, garnered from images of Saturn's most massive ring, the B ring, may answer another long-standing question: What causes the...

Scientists using NASA's Cassini spacecraft at Saturn have stalked a new class of moons in the rings of Saturn that create distinctive propeller-shaped gaps in ring material. It marks the first time scientists have been able to track the orbits of individual objects in a debris disk. The research gives scientists an opportunity to time-travel back into the history of our solar system to reveal clues about disks around other stars in our universe that are too far away to observe directly....

Newly released images from last November's swoop over Saturn's icy moon Enceladus by NASA's Cassini spacecraft reveal a forest of new jets spraying from prominent fractures crossing the south polar region and yield the most detailed temperature map to date of one fracture. The new images from the imaging science subsystem and the composite infrared spectrometer teams also include the best 3-D image ever obtained of a "tiger stripe," a fissure that sprays icy particles, water vapor and organic...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
