The Eyes Galaxies (NGC 4435-NGC 4438, also known as Arp 120) are a pair of galaxies about 52 million light-years away in the constellation Virgo. NGC 4438 is the most curious interacting galaxy in the Virgo Cluster, due to the uncertainty surrounding the energy mechanism that heats the nuclear source; this energy is a monstrous Black Hole embedded in an active galactic nucleus (AGN) - blowing huge bubbles of hot gas into space. Known as a peculiar galaxy because of its unusual shape, NGC 4438 is in the Virgo Cluster.

Additionally, there is evidence to suggest that the environmental damage to the interstellar medium of NGC 4438 may have been caused by an encounter (off-center collision) with NGC 4435, millions of years ago.
