First light for WISE
First light for WISE This infrared snapshot of a region in the constellation Carina near the Milky Way was taken shortly after NASA's Wide-field Infrared Survey Explorer (WISE) ejected its cover. The "first light" picture shows thousands of stars and covers an area three times the size of the moon. WISE will take more than a million similar pictures covering the whole sky. This eight-second exposure shows infrared light from three of WISE's four wavelength bands: Blue, green and red correspond to 3.4, 4.6, and 12 microns, respectively. NASA / JPL / UCLA
