The largest structures in the Universe are superclusters: not just clusters of galaxies, but clusters<\/em> of clusters. They can stretch for millions of light years and be composed of thousands of galaxies. <\/p>

Abell 2744, at a distance from Earth of about 3.5 billion light years, is one such megastructure (if you want to sound fancy, astronomers call it \"large-scale structure\"). Astronomers have been studying Abell 2744 with an arsenal of telescopes, and have discovered<\/a> that it’s actually the result of the ongoing collision of four<\/em> galaxies clusters. If you’ve ever wondered what 400 trillion<\/em> solar masses of material<\/strong> slamming into each other looks like, well, it’s more than a bit of a mess<\/a>:<\/p>

Yeah, like I said, it’s a mess.<\/p>

First off, this picture is a combination of observations from Hubble (in visible light, colored blue, green, and red), the Very Large Telescope (also blue, green, and red), and the Chandra X-Ray Observatory (X-rays, colored pinkish). In visible light you can see literally hundreds of galaxies, probably more, dotting the supercluster. The pink glow is from very hot gas between galaxies; it started its life ...<\/p>
