Clusters of galaxies are larger, and we now know that clusters of clusters exist. Furthermore, we shouldn’t forget the most turbulent event of all—the big bang. Let’s begin by considering cluste

In the last few years, astronomers have been able to do this, and they have found a fascinating structure. You would, of course, expect voids and superclusters. But they have fo

Roland Schauer,Anthony P. CorfieldAnd so we come to the end of our story. In our journey through the universe we have seen an amazing array of objects: exploding galaxies (some with powerful jets), colliding and interacting galaxies with huge tidal plumes emanating from them, and quasars—distant and mysterious. Each is an awe-inspiring spectacle.

Quasars,It might be hard to believe that something even more powerful and more energetic than a radio galaxy could exist. But it does. In the early 1960s extremely energetic objects that we now call quasars were discovered.

Galaxies,thought they were huge clouds of gas that were relatively nearby, and a few even thought that they might be the first stages of planetary systems. Many years would pass, though, before the argument would be resolved. Telescopes were still too crude at this stage to provide a solution to the mystery.

Colliding Galaxies: The Discovery,two galaxies. We saw earlier that Cygnus A was initially thought to be two galaxies in collision. And although we now know this isn’t the case, we also know that there are galaxies that are interacting, and in some cases actually colliding and merging.

To the Ends of the Universe,und much more. The whole universe seems to be filled with voids; in fact, they are more like gigantic bubbles. And strung along the surface of these bubbles are superclusters. It sounds crazy, but on this scale, the universe looks like a sink full of soapsuds.
