Description

The Hickson 93 Galaxy Group, also referred to as Arp 99, can be found in the constellation Pegasus. From the Atlas of Compact Groups of Galaxies (1993), Paul Hickson stated, “This group (Arp 99) consists of an accordant quartet plus a fainter high-redshift galaxy. The bright spiral galaxy has two long plumes which result from tidal interaction. It is a radio and infrared source. The bright elliptical galaxy is also a radio source.”
This grouping is about 265 million light years away, five main galaxies are shown in the image, but only four are thought to be gravitationally bound and strongly interacting. You can see in the image how NGC 7549 is distorted by gravity, slowly pulling away strings of stars and gas.
