NGC 1427A is a dwarf irregular galaxy of more than 20,000 light-years long that lies about 52 million light-years away from Earth in the constellation of Eridanus, while it is receding from us at roughly 2028 kilometers per second. It is the brightest dwarf irregular member of the Fornax Cluster, a group of 58 galaxies.

What Is A Irregular Galaxy ??
An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. The shape of an irregular galaxy is uncommon – they do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.
Collectively they are thought to make up about a quarter of all galaxies. Some irregular galaxies were once spiral or elliptical galaxies but were deformed by disorders in gravitational pull. Irregular galaxies may contain abundant amounts of gas and dust. This is not necessarily true for Dwarf Irregulars.
