The New General Catalogue of Nebulae and Clusters of Stars (abbreviated as NGC) is a catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, known as the NGC objects. It is one of the largest comprehensive catalogues, as it includes all types of deep space objects, including galaxies, star clusters, emission nebulae and absorption nebulae.

NGC 7640
NGC 7640 is a barred spiral galaxy in the constellation of Andromeda. Discovered on October 17, 1786 by the English astronomer William Herschel. The galaxy has an 11th visible magnitude and is located about 30 million light-years from Earth. NGC 7640 might not look much like a spiral, but this is due to the orientation (edge on) of the galaxy with respect to an observer on Earth. There is evidence that this galaxy has experienced an interaction with another galaxy in the (astronomically) recent past.
