Summary

DescriptionAbell S0740 HST det.jpg	This NASA Hubble Space Telescope image shows the diverse collection of galaxies in a galaxy cluster called Abell S0740, located more than 450 million light-years away in the constellation Centaurus. The giant elliptical galaxy ESO 325-G004 looms large at the cluster's center. This galaxy is as massive as 100 billion suns. Hubble resolves thousands of globular star clusters orbiting ESO 325-G004. Globular clusters are compact groups of hundreds of thousands of stars that are gravitationally bound together. At the galaxy's distance they appear as pinpoints of light contained within the diffuse halo. Other elliptical and spiral galaxies appear in the image. The photo was made from images taken using Hubble's Advanced Camera for Surveys in January 2005 and February 2006. Object Name: ESO 325-G004, Abell S0740 Object Description: Giant Elliptical Galaxy and its Host Galaxy Cluster Position (J2000): R.A. 13h 43m 33s.30 Dec. -38° 10' 34".0 Constellation: Centaurus Distance: Approximately 463 million light-years (142 Megaparsecs) Dimensions: This image is roughy 2.9 arcminutes (385,000 light-years or 120 kiloparsecs) wide.
