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]

APOD turns seven. The Astronomy Picture of the Day hit the seven-year mark on Sunday (full archive list here). Simple and consistent in design, (possibly a record-holder for longest consistent design of an updated site) it's still maintained by astronomers Robert Nemiroff and Jerry Bonnell.
