Astronomers have recently discovered a large cluster of galaxies now known as the supercluster Hyperion. Hyperion is thought to have formed only 2 billion years after the big bang, making this the largest structure of galaxies ever observed in the early universe.
Hyperion was discovered by a team of international scientists who were surprised to see something so large and so evolved from when the universe was still so young.
“When you are studying galaxies something that is 2 billion years old is very young.” Lowell Astronomer Deidre Hunter explains. “It’s only 1/14th the age of the universe. If you think of it as the life of a human it would only be 10 or 15 years old.”
Which leaves you wondering how do clusters and superclusters like Hyperion form?
“An individual galaxy you see is a bunch of gas and stars rotating around the center.” Hunter states. “Then you are just looking for concentrations. When you have enough galaxies together you get a cluster. When you see a cluster of clusters that’s what we call a supercluster.”
For a galaxy to be formed you need something to pull everything together. That something is gravity. Just ...
