Abell 1060 CHI-1 bundle

The Hydra Cluster (or Abell 1060) is a galaxy cluster located in the constellation Hydra that contains 157 bright galaxies. It spans about ten million light-years and has an unusually high proportion of dark matter. The cluster is part of the Hydra-Centaurus Supercluster located 158 million light-years from Earth.
The largest galaxies are the elliptical galaxies NGC 3309 and NGC 3311 and the spiral galaxy NGC 3312 all having a diameter of about 150,000 light-years. In spite of a nearly circular appearance on the sky, there is evidence in the galaxy velocities for a clumpy, three-dimensional distribution.
