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 1574


NGC 1574 is a lenticular galaxy in the constellation Reticulum. The galaxy lies about 55 million light years away from Earth, which means, given its apparent dimensions, that NGC 1574 is approximately 75,000 light years across. It was discovered by John Herschel on December 4, 1834. It is a member of the Dorado Group. The galaxy features a bar embedded in an extended disk. A nearly complete ring surrounds the bar. The galaxy is seen nearly face-on, at an inclination of about 27°. Carbon monoxide gas has been lying in a disk about 2.6 arcseconds across, which corresponds to about 200 parsecs, around the nucleus. The kinematics suggest that it is due to a warp in the disk. The nucleus of the galaxy doesn't appear to be active. The supermassive black hole is estimated to have a mass of (1.0±0.2)×108 M☉.
