It's an awesome pic. There looks to be a sun-dolphin leaping thru the flames...

 The above image was sent back by the Cassini spacecraft! |

Cassini Images Bizarre Hexagon on SaturnMarch 27, 2007 Pasadena, Calif. -- An odd, six-sided, honeycomb-shaped feature circling the entire north pole of Saturn has captured the interest of scientists with NASA's Cassini mission. NASA's Voyager 1 and 2 spacecraft imaged the feature over two decades ago. The fact that it has appeared in Cassini images indicates that it is a long-lived feature. A second hexagon, significantly darker than the brighter historical feature, is also visible in the Cassini pictures. The spacecraft's visual and infrared mapping spectrometer is the first instrument to capture the entire hexagon feature in one image. "This is a very strange feature, lying in a precise geometric fashion with six nearly equally straight sides," said Kevin Baines, atmospheric expert and member of Cassini's visual and infrared mapping spectrometer team at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "We've never seen anything like this on any other planet. Indeed, Saturn's thick atmosphere where circularly-shaped waves and convective cells dominate is perhaps the last place you'd expect to see such a six-sided geometric figure, yet there it is." The hexagon is similar to Earth's polar vortex, which has winds blowing in a circular pattern around the polar region. On Saturn, the vortex has a hexagonal rather than circular shape. The hexagon is nearly 25,000 kilometers (15,000 miles) across. Nearly four Earths could fit inside it. The new images taken in thermal-infrared light show the hexagon extends much deeper down into the atmosphere than previously expected, some 100 kilometers (60 miles) below the cloud tops. A system of clouds lies within the hexagon. The clouds appear to be whipping around the hexagon like cars on a racetrack. "It's amazing to see such striking differences on opposite ends of Saturn's poles," said Bob Brown, team leader of the Cassini visual and infrared mapping spectrometer, University of Arizona, Tucson. "At the south pole we have what appears to be a hurricane with a giant eye, and at the north pole of Saturn we have this geometric feature, which is completely different." The Saturn north pole hexagon has not been visible to Cassini's visual cameras, because it's winter in that area, so the hexagon is under the cover of the long polar night, which lasts about 15 years. The infrared mapping spectrometer can image Saturn in both daytime and nighttime conditions and see deep inside. It imaged the feature with thermal wavelengths near 5 microns (seven times the wavelength visible to the human eye) during a 12-day period beginning on Oct. 30, 2006. As winter wanes over the next two years, the feature may become visible to the visual cameras. Based on the new images and more information on the depth of the feature, scientists think it is not linked to Saturn's radio emissions or to auroral activity, as once contemplated, even though Saturn's northern aurora lies nearly overhead. The hexagon appears to have remained fixed with Saturn's rotation rate and axis since first glimpsed by Voyager 26 years ago. The actual rotation rate of Saturn is still uncertain. "Once we understand its dynamical nature, this long-lived, deep-seated polar hexagon may give us a clue to the true rotation rate of the deep atmosphere and perhaps the interior," added Baines. The hexagon images and movie, including the north polar auroras are available at: www.nasa.gov/cassini and saturn.jpl.nasa.gov and wwwvims.lpl.arizona.edu . The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter was designed, developed and assembled at JPL. The Visual and Infrared Mapping Spectrometer team is based at the University of Arizona. ---------------------------------------------- www.jpl.nasa.gov/news/news.cfm?release=2007-034

Yeah, I saw that, Thorn. A god's eye at Saturn's north pole! And it's not new, but long-lived. I've read about it, but I haven't seen anyone explain how the hell it happens. Freaky!

Personally, I think it's the Gateway calling the Honeybees back home!

i think the bees are being kidnapped by my nemesis, whose name is unmentionable. we need to call in the pet detective.

I snapped this picture of Saturn tonight from my driveway...  Not very good, but this was my first attempt. I was just starting to get some good results when it clouded up. Yeah, now that we have spacecraft that fly right by and take beautiful detailed pictures, it's pretty lame. But think: this is from my driveway with an affordable digital camera and a modest telescope. It didn't cost millions, y'know! You can see a little of the rings' shadows on the planet. And that's what it looks like from here under those conditions! I will improve upon these results, too! There is still nothing like when you are looking at it yourself, with your own eyes! I was able to to resolve Cassini's division (the gap in the rings), too! |

My best friend has a nice 8 inch Meade and the cool camera for Astro Photography. We do the amateur astronomy club thing here and he captured this. I was standing right beside him to go "cool", "great job" because I can't afford a new telescope right now with those awesome capabilities. Still, here's the moon, which is my favorite thing to look at. This is an awesome thread by the way.  |
