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 2525


NGC 2525 is a barred spiral galaxy located in the constellation Puppis. It is located at a distance of about 70 million light years from Earth, which, given its apparent dimensions, means that NGC 2525 is about 60,000 light years across. It was discovered by William Herschel on February 23, 1791. The galaxy has a bar and two main spiral arms with high surface brightness. HII regions are observed in the arms. The brightest stars of the galaxy have apparent magnitude around 22. Its nucleus is small and bright. In the centre of the galaxy is predicted to lie a supermassive black hole whose age is estimated to be between 1.1 and 44 million years, based on the spiral arm pitch angle.
