Hydra Cluster

Hydra Cluster
(Image and Text Credit: ROSAT/MPE)

ROSAT observation of the galaxy cluster in the constellation Hydra. The X-ray intensity map taken with ROSAT is superposed onto the optical image of the central part of the cluster. The maximum of the X-ray emission coincides with the position of the two brightest elliptical galaxies at the center of the cluster. With a distance of approximately 200 million light years and a mass of nearly 4 x 1015 solar masses this galaxy cluster contributes to the gravitational attraction of the so-called Great Attractor.
