On the morning of February 1st, 2011, NASAs Wide-field Infrared Survey Explorer, or WISE, took its last snapshot of the sky. This last light image is reminiscent of the first light image from WISE, taken only 13 months prior. WISEs final picture shows thousands of stars in a patch of the Milky Way Galaxy, covering an area 3 times the size of the full Moon, in the constellation Perseus. In the upper left corner, a faint wispy cloud can be seen bending around a pulsating variable star called EV Persei.

After its coolant ran out in October of 2010, WISE warmed up from -260 degrees to -200 degrees C (-436 to -328 degrees Fahrenheit). This image contains data from the two detectors largely unaffected by the warm-up: 3.4 and 4.6 microns (the 12 and 22 micron detectors are no longer useful at the warmer temperatures). The color is representational: cyan (blue-green) shows light detected by the 3.4 micron channel of WISE, and red shows light seen by the 4.6 micron channel. This region of the sky had been observed by WISE previously in all four of its detectors as part of its primary survey, and it is hard to see any difference in the quality of the last-light images at 3.4 and 4.6 microns.

In the short 13 months that WISE surveyed, it produced millions of infrared images covering the whole sky in its four bands, and covering it twice at 3.4 and 4.6 microns. Now that the survey is complete, WISE is being put into hibernation. While the satellite sleeps and circles more than 500 kilometers above the Earths surface, the WISE team is busily preparing its data for two big public releases: one this April, and the final release in the spring of 2012. Even though WISE has taken its last picture, the project will continue to feature some of the best imagery from the survey on a regular basis.
