Cartwheel galaxy makes waves

The Cartwheel galaxy, which is found in the constellation Sculptor in the Southern Hemisphere below Pisces and Cetus, resulted from a 200-million-year-old collision between two galaxies. This image is the result of NASA's many instruments: the Galaxy Evolution Explorer's Far Ultraviolet detector (blue), the Hubble Space Telescope's Wide Field and Planetary Camera-2 in B-band visible light (green), the Spitzer Space Telescope's Infrared Array Camera (red) and the Chandra X-ray Observatory's Advanced CCD Imaging Spectrometer-S array instrument (purple).
