The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues (abbreviated IC), describing a further 5,386 astronomical objects. Thousands of these objects are best known by their NGC or IC numbers, which remain in widespread use.
This is a list of NGC objects 1–1000 from the New General Catalogue (NGC). The astronomical catalogue is composed mainly of star clusters , nebulae , and galaxies . Other objects in the catalogue can be found in the other subpages of the list of NGC objects .
The Wild Duck Cluster (also known as Messier 11, or NGC 6705) is an open cluster of stars in the constellation Scutum (the Shield). It was discovered by Gottfried Kirch in 1681. [ 3 ] Charles Messier included it in his catalogue of diffuse objects in 1764.
NGC 2566 is a barred spiral galaxy in the constellation of Puppis. Its velocity with respect to the cosmic microwave background is 1898 ± 19 km/s, which corresponds to a Hubble distance of 91.3 ± 6.5 Mly (28.00 ± 1.98 Mpc). [1] However, five non-redshift measurements give a much closer distance of 35.39 ± 8.42 Mly (10.852 ± 2.583 Mpc). [2]
NGC 1 and NGC 2 as an optical double NGC 2 is located about 345 million light-years from the Solar System , with a magnitude of +14.2, while the distance to NGC 1 is 210 million light-years. Although visually close in the sky, NGC 1 and NGC 2 are at very different distances; were they stars, they would be referred to as an " optical double " as ...
The Catalogue of Nebulae and Clusters of Stars was first published in 1786 by William Herschel in the Philosophical Transactions of the Royal Society of London. [1] In 1789, he added another 1,000 entries, [2] and finally another 500 in 1802, [3] bringing the total to 2,500 entries.
