This composite shows the Antennae galaxies in Corvus with data on hot gas from the Chandra X-ray Observatory in blue, on stars and cool dust from the Hubble Space Telescope in gold and brown, and on warm dust from the Spitzer Space Telescope in red. The these colliding galaxies take their name from the long antenna-like "arms" seen in wide-angle images, produced by tidal forces generated in the mash-up.
