Hickson 40 is a well-known galaxy group[1] in the constellation Hydra. It consists of 6[citation needed] separate members (three spiral galaxies, an elliptical galaxy, and a lenticular galaxy[1]) and is in the stage of merging. Member galaxies of Hickson 40 interacted in the early stages of their formation to create a crowded galaxy sampler. Hickson 40 resides at a distance of 300 million light years[1] and is so dense[2] that it could exist within a region close to the diameter of the Milky Way's galactic disk.[3]
