A giant collision of several galaxy clusters, each containing hundreds of galaxies, has produced this spectacular panorama of shocks and energy. The collisions generated shock waves that set off a celestial fireworks display of bright radio emission, seen as red and orange. The new VLA observations revealed previously undetected regions where shocks accelerated subatomic particles, causing radio emission. Currently, they said, evidence indicates a North-South collision of subclusters and an East-West (left-right in the image) collision. There is a possible third collision, and the astronomers continue to analyze their data to uncover more details about the region's complex history of collisions and their aftermath.
