Scientists have now officially witnessed the perfect cosmic storm. Thanks to the European Space Agency's XMM-Newton observatory, they watched a nearby head-on collision between two galaxy clusters. The clusters smashed together thousands of galaxies and trillions of stars in one of the most powerful events ever witnessed.
