Description

NGC 4449 (also known as Caldwell 21) is an irregular galaxy in the constellation Canes Venatici. It is located about 12 million light-years away, part of the M94 Group (the Canes Venatici I Group), a galaxy group relatively close to the Local Group containing the Milky Way. This well-studied galaxy is similar in size and brightness, and often compared to, the Milky Way's satellite galaxy, the Large Magellanic Cloud (LMC).[3] NGC 4449 has a general bar shape, also characteristic of the LMC, with scattered young blue star clusters. NGC 4449 is surrounded by a large envelope of neutral hydrogen that extends over an area of 75 arc minutes −14 times larguer than the optical diameter of the galaxy- that show distorsions and irregularities likely caused by interactions with nearby galaxies.
