HUBBLE ILLUMINATES CLUSTER OF DIVERSE GALAXIES
This image from NASA's Hubble Space Telescope shows
the diverse collection of galaxies in the cluster
Abell S0740 that is over 450 million light-years
away in the direction of the constellation Centaurus.
The giant elliptical ESO 325-G004 looms large at
the cluster's center. The galaxy is as massive as
100 billion of our 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
Other fuzzy elliptical galaxies dot the image.
Some have evidence of a disk or ring structure that
gives them a bow-tie shape. Several spiral galaxies
are also present. The starlight in these galaxies
is mainly contained in a disk and follows along
This image was created by combining Hubble science
observations taken in January 2005 with Hubble Heritage
observations taken a year later to form a 3-color
composite. The filters that isolate blue, red and
infrared light were used with the Advanced Camera
for Surveys aboard Hubble.
