A Galactic Particle Collider And An Image Of 10,000 Galaxies

I just got back from a local art fair, so it occurs to me that the Hubble is kind of like its own ready-made exhibit. I get lost in those images more than any paintings or sculptures, and space never fails to generate paradoxes and mind-boggling patterns. Today’s space news involves two such offerings: a particle collider and the best picture of the Milky Way, along with thousands of other galaxies.

While we have painstakingly created our own impressive particle colliders, the cosmos can do us one better. Five billion light years away, there’s a collision of galaxy clusters that are forming an accelerator estimated to be a million times stronger than the Large Hadron Collider. Clusters of this sort are the largest structures in the universe, and can consist of thousands of galaxies that continue piling up over billions of years as a result of collisions between smaller groupings.
