 The Hydra supercluster is close to the Virgo supercluster and similar in size and shape to it. It's about 100 million light-years long and contains the large Hydra Galaxy cluster. This map plots every bright galaxy in the supercluster. The galaxies in the supercluster range from 150 to 200 million light-years away. Here's a picture of the Hydra cluster. Two stars within our own Milky Way galaxy can be seen in the foreground. There are three large galaxies near the cluster center. Two yellow ellipticals and one prominent blue spiral. These are the dominant galaxies, each about 150,000 light-years in diameter. And here's an interesting overlapping galaxy pair catalogued as NGC 3314. We'll take a closer look at this one.
