This picture of NGC 1706, taken by the NASA/ESA Hubble House Telescope, is an efficient instance of this. NGC 1706 is a spiral galaxy, about 230 million light-years away, within the constellation of Dorado (the Swordfish).

NGC 1706 is understood to belong to one thing generally known as a galaxy group, which is simply because the title suggests—a gaggle of as much as 50 galaxies that are gravitationally certain and therefore comparatively shut to one another. Round half of the galaxies we all know of within the universe belong to some type of group, making them extremely frequent cosmic buildings. Our dwelling galaxy, the Milky Manner, belongs to the Native Group, which additionally incorporates the Andromeda galaxy, the Giant and Small Magellanic clouds, and the Triangulum galaxy.

Teams are the smallest of galactic gatherings; others are clusters, which may comprise lots of of hundreds of galaxies certain loosely collectively by gravity, and subsequent superclusters, which convey collectively quite a few clusters right into a single entity.
