NGC-253, Spiral galaxy in Sculptor
NGC-253 is a large, much elongated spiral galaxy located in the southern constellation of Sculptor. If not for its extreme southern declination (-25 degrees) it would be one of the showpiece deep sky objects in the northern sky. It resembles a smaller version of M-31, the Andromeda Galaxy. It is a member of the Sculptor group of galaxies and lies only 11 million light years from Earth. It is 90,000 light years in diameter and contains 100 billion suns. NGC-253 was discovered by Caroline Herschel while she was searching for comets. NGC-253 is dominated by a network of complex dust lanes, and is also undergoing intense star formation.
