You may already be familiar with PhDComics (Previously) and the PhDMovie (Previously), but PhDComics.tv has now become a pretty fantastic resource for both researchers and laymen. [more inside]
On July 17th, NASA's Wide-field Infrared Survey Explorer (WISE) satellite completed its first survey of the entire sky viewable from Earth. After just seven months in orbit, WISE -- a precursor to the planned James Webb Space Telescope -- has returned more than a million images that provide a close look at celestial objects ranging from distant galaxies to asteroids. The first release of WISE data, covering about 80 percent of the sky, will be delivered to the astronomical community in May of next year, but in the meantime we can see some of the images and animations that NASA has released to date: Galleries (containing just a small selection of images): 1, 2, 3, 4. Videos and Animations: 1, 2 [more inside]
Stunningly beautiful photo of Dione and Saturn with rings. Such a sensation of depth and grandeur. Thanks, Cassini/JPL/NASA. [animation] [planetary photojournal entry] [B/W mirror from kokogiak] [now you play fun Flash spaceship game].
Cassini Flies by Tethys and Hyperion, and the photos so far have been awesome and weird. I especially want to point out this fascinating view, which, if you look at it closely, reveals what appears to be a string of small impact craters, in a straight line over older terrain. What kind of meteor impact could have produced such an excellent formation of craters? Hyperion photos are coming. (Kokogiak's got backup in case the JRUNS strike.)
Two Moons Passing in the Night. Mars rover Spirit took these sequential photos of Martian moons Phobos and Deimos passing overhead in the night sky. Those rovers are still going strong!
Rocks Among the Rings. The Planetary Society's Emily Lakdawalla has compiled some of the loveliest imagery of Saturn's ring-and-moon system from Cassini. More on Saturn from the Planetary Society here. Also see the Cassini at Saturn photoset, from our very own kokogiak, and watch for updates on the latest Enceladus flyby.
