Also during its first-light flight in 2010, SOFIA captured a composite image of the center of starburst galaxy M82 in Ursa Major at wavelengths of 20, 32, and 37 microns (colored blue, green, and red, respectively). The middle and top images show the same part of the galaxy at visual wavelengths. Because infrared light penetrates its dust clouds, those images reveal the star-forming heart of the galaxy.
