WISE Guys (and Gals) At Work


The WISE (Wide-Field Infrared Explorer) mission team has put together these 4 images to celebrate the one year anniversary of the WISE launch. Upper left is NGC 300, a much studied spiral galaxy. Upper right is M104 aka the Sombrero Galaxy, another spiral but seen nearly edge-on. Lower is M60, an elliptical galaxy 20% larger than the Milky Way. The lower right is M51 or the Whirlpool galaxy, a “grand design” spiral galaxy. To make these images from infrared data, Wavelength os 3.4 microns were colored blue, 4.6 microns became cyan, 12 microns to green, and 22 microns to red.
