Abell 2151 - Herclules Galaxy Cluster

In this 'small' section of space, lies approximately 200 galaxies, many of which are interacting. This cluster is part of a larger supercluster, and that supercluster is part of the much larger "Great Wall Super-Structure"

Distance from Earth is approximately 500 million light-years, and found in the constellation of Hercules.

Here are some of its key features:
Dense and Populous - Abell 2151 is estimated to contain around 200 galaxies, spread across a region roughly 6 million light-years in diameter.
Spiral Galaxy Rich: Unlike many galaxy clusters, which tend to be dominated by elliptical galaxies, Abell 2151 has a surprising number of spiral galaxies.
A Galaxy Zoo: This cluster is known for its many interacting galaxies, where galaxies have gotten close enough to gravitationally tug on each other, distorting their shapes. Some of these interactions are so dramatic that several galaxies from Abell 2151 are included in the Arp Atlas of Peculiar Galaxies
