Loose grouping of galaxies with many yellow-ish elliptical galaxies and one priminent spiral galaxy

Fornax Galaxy Cluster

Caption: Galaxies can reside in groups, such as our own local group, or in clusters of galaxies. The Fornax Galaxy Cluster is one of the nearest such large groupings of galaxies. Visible in this image taken by the Very Large Telescope Survey Telescope VST (at the European Southern Observatory in Chile) are elliptical galaxies (without defined structures and in a yellow tint) but also spiral galaxies such as NGC 1365 towards the bottom right. This galaxy in particular is classified as a barred spiral galaxy due to its prominent and well-defined bar. The center of the Fornax Cluster is the giant elliptical galaxy NGC 1399, visible as the largest galaxy on the left of the image.

A large yellow oval galaxy sits in a field of many smaller galaxies. This large galaxy is brightest in its core

The giant elliptical galaxy ESO 325-G004

Caption: The giant elliptical galaxy ESO 325-G004 sits in the Abell S0740 galaxy cluster. This huge galaxy has a mass of approximately a hundred billion solar masses. ESO 325-G004 is brightest in its core with its brightness decreasing further from its center. This galaxy has no visible spiral structure or dust lanes. ESO 325-G004 and many of the smaller galaxies around it are members of the galaxy cluster Abell S0740.
