Pandora Galaxy

Here's another of those science-beating-art-at-its-own-game images which show Heaven in its immense violence and beauty. There's a lot of hi-tech jiggery-pokery behind this image, as you can tell by its credits: NASA /ESA /ESO /CXC /D COE /J MERTEN. It depicts a cosmic collision in the Pandora Galaxy Cluster - officially known as Abell 2744 - which has been ongoing for 350 million years! (Creationists take note.) The artificial colours engulfing these scattered galaxies are red for hot gases and blue for dark matter. Caught at the right moment, such images help scientists figure out what dark matter is and what it's doing (title link).
