NGC 2207
A false-color photograph of interacting galaxies. This picture consists of infrared images taken with IRAC (the SAO-led camera on NASA's Spitzer Space Telescope; red color), and visible images from NASA's Hubble Space Telescope (blue/green colors). These two galaxies began their collision about 40 million years ago: as they tug at each other, the disrupted gas prompts new stars to form. Eventually the galaxies will meld into one.
