When Galaxy Clusters Collide - UNIVERSE


There is a deep connection between some of the largest, most energetic events in the universe and much smaller, weaker ones powered by our own Sun.

The results come from a long observation with NASA's Chandra X-ray Observatory of Abell 2146, a pair of colliding galaxy clusters located about 2.8 billion light years from Earth.

Galaxy clusters contain hundreds of galaxies and huge amounts of hot gas and dark matter and are among the largest structures in the universe. Collisions between galaxy clusters release enormous amounts of energy unlike anything witnessed since the big bang and provide scientists with physics laboratories that are unavailable here on Earth.
