Professional and amateur astronomers will spend decades poring over a massive data-dump from NASA that represents 57% of the take from the Wide-field Infrared Survey Explorer (WISE) mission, which imaged the entire sky from polar orbit. There are millions of objects in the survey data that have never been detected before, as well as spectacular views of objects in four infrared wavelengths. In all, WISE collected more than 2.7 million images as it surveyed all of the sky at least once and another half of it again before the mission was terminated. In this Aitoff projection, the center of the Milky Way galaxy is at the center of the oval, blue and blue-green represent objects-typically stars-detected in the 3.4- and 4.6-micron wavelengths, and green and red signify mostly warm dust in the 12- and 22-micron wavelengths. The gray blanks represent data not included in the first release.
