Antennae galaxies

The NGC 4038 Group is a group of galaxies in the constellations Corvus and Crater. The group may contain between 13 and 27 galaxies. The group's best known galaxies are the Antennae Galaxies (NGC 4038/NGC4039), a well-known interacting pair of galaxies.

Additionally, the references above frequently but inconsistently identify PGC 37513, PGC 37565, and UGCA 270 as members of this group. Based on the above references, the exact membership of this group is somewhat uncertain as is the exact number of galaxies within the group.

Location

The NGC 4038 group along with other galaxies and galaxy groups [4] are part of the Crater Cloud [6] [7] which is a component of the Virgo Supercluster. [6]

NGC 4631 is a barred spiral galaxy in the constellation Canes Venatici about 30 million light years away from Earth. This galaxy's slightly distorted wedge shape gives it the appearance of a herring or a whale, hence its nickname. Because this nearby galaxy is seen edge-on from Earth, professional astronomers observe this galaxy to better understand the gas and stars located outside the plane of the galaxy.
