The Galaxy Menagerie from WISE

A new, colorful collection of galaxy specimens has been released by NASA's Wide-field Infrared Survey Explorer, or WISE, mission. It showcases galaxies of several types, from elegant grand design spirals to more patchy flocculent spirals. Some of the galaxies have roundish centers, while others have elongated central bars. The orientation of the galaxies varies as well, with some seeming to peer straight back at us in the face-on configuration while others point to the side, appearing edge-on.

Infrared light has been translated into colors we see with our eyes, such that the shortest wavelengths are blue and the longest are red. The oldest stars appear blue, while pockets of newly formed stars have yellow or reddish hues.
