NASA’s Wide-Field Infrared Survey Explorer, or WISE, highlights the Andromeda Galaxy in one of the first images sent down from orbit. This image, released Feb. 17, combines data from all four of WISE’s infrared detectors. Shades of blue highlight mature stars. The yellow and red areas indicate where dust has been heated by newborn, massive stars.
