What does NGC mean in the Milky Way galaxy?

New General Catalogue
Bob Fera. Any amateur astronomer who has read about the universe or has an interest in observing deep-sky objects has encountered the letters NGC. They stand for New General Catalogue. The complete title is New General Catalogue of Nebulae and Clusters of Stars.

Why are there no comets in the Messier Catalogue?

Upon further observation, he realized that the object could not be a comet because it was not moving across the sky. By the time of his death in 1817, Messier had compiled a list of 103 objects in the night sky using his own observations with various telescopes and the discoveries of other astronomers.

What was the initial purpose of the Messier catalog?

The first of the Messier objects to be observed by Messier was the remnant of a supernova explosion known as the Crab Nebula (M1). Over the next few years, Messier and his colleagues would catalog a total of 110 nebulae, galaxies, and star clusters. Today, the Messier Catalog is a valuable tool for amateur astronomers.

Who Catalogued M104 full name?

Herschel catalogued the object as H I. 43 and described it as “extended” and “very bright toward the middle.” John Herschel catalogued M104 as h 1376 and later included it in the General Catalogue as GC 3132.

Why galaxies are called NGC?

For example, NGC 7331, a galaxy that has been called a twin of the Milky Way because of its similarity. The NGC catalog is short for New General Catalogue, and it’s a list of 7,840 interesting objects in the night sky. Many galaxies are named after the constellation they’re located in.

Who Catalogued M101?

Pierre Méchain, one of Charles Messier’s colleagues, discovered the Pinwheel galaxy in 1781. Located 25 million light-years away from Earth in the constellation Ursa Major, M101 has an apparent magnitude of 7.9. It can be spotted through a small telescope and is most easily observed during April.

What does the M in M104 stand for?

Sombrero Galaxy
Other designations. M104, NGC 4594, UGC 293, PGC 42407. The Sombrero Galaxy (also known as Messier Object 104, M104 or NGC 4594) is a spiral galaxy in the constellation borders of Virgo and Corvus, being about 9.55 megaparsecs (31.1 million light-years) from our galaxy, within the local supercluster.

Who named M104?

M104 was discovered in 1781 by the French astronomer and comet hunter Pierre Méchain, one of Charles Messier’s colleagues. For more information about Hubble’s observation of M104, see: Heritage Project Celebrates Five Years of Harvesting the Best Images from Hubble Space Telescope.
