NGC 253 is a starburst galaxy, which means that it is currently undergoing a period of intense star formation. It is the brightest member of the Sculptor group of galaxies, which is grouped around the South galactic pole. The Sculptor group is perhaps the nearest to our Local Group of galaxies.This Galaxy is also one of the brightest galaxies beyond the Local Group. NGC 253 is also known as the Silver Coin Galaxy; and is also referred to as the Sculptor Galaxy.
Yhis Galaxy was one of the major discoveries of Caroline Herschel, the sister of William Herschel. She discovered this object on September 23, 1783 with "an excellent small Newtonian Sweeper" of 27 inches focal length and a power of 30 (William Herschel's description), and added it to her list as No. 10. William Herschel included it in his catalog as No. V.1.
One supernova has been discovered in this Galaxy up to now: SN 1940E, which was discovered by Fritz Zwicky 51"W 21"S of the galaxy's nucleus, and became as bright as 14.0 mag (announced in IAUC 848).
NGC 253 is approximately 8 million Light Years from Earth.
