What is the largest structure in the universe?

Hamlet.

The largest structures in the universe are superclusters, which are large associations of galaxies that can extend over distances of more than 100 million light-years. I just did a quick search through the literature, and the largest supercluster on which I was able to find any information is the Sculptor Supercluster, which, according to the supercluster catalog compiled by a group of astronomers at Tartu Observatory in Estonia and the IUE Observatory in Spain, is nearly 1 billion light-years away, and extends roughly 250 million light-years from end to end. That's not to say that there might not be some larger superclusters out there, but astronomers don't have any reason to believe that there are any structures bigger than superclusters.

Given that the universe is a structure, and by definition must be in the universe, or at least occupies the space of the universe, then I'd say it is THE UNIVERSE. However on a serious note, the answer Peasy is looking for is the huge sheet of galaxies forming a large-scale pattern of supergalactic structure called the "Great Wall" of the universe. It measures 700,000,000 light years by 200,000,000 light years by 20 light years. Feb 16 04, 7:12 PM
