WISE Studies Our Neighbor Andromeda
The immense Andromeda galaxy, also known as Messier 31 or simply M31, is captured in this image from NASA's Wide-field Infrared Survey Explorer (WISE). WISE used all four of its infrared detectors to capture this picture: 3.4- and 4.6-micron light is blue; 12-micron light is green; and 22-micron light is red. Blue highlights mature stars, while yellow and red show dust heated by newborn, massive stars.
