NGC 3370 (also known as UGC 5887 or Silverado Galaxy [2] ) is a spiral galaxy about 82.2 ± 5.9 million light-years (25.2 ± 1.8 megaparsecs ) away in the constellation Leo. It is nearly comparable to our Milky Way both in diameter with a D25 isophotal size about 77,300 ly (23.69 kpc) comparing to the Milky Way Galaxy's 87,400 ly (26.8 kpc) diameter, and as well as in mass (1011  M ).[ citation needed ] NGC 3370 exhibits an intricate spiral arm structure surrounding a poorly defined nucleus. It is a member of the NGC 3370 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster. [3]

NGC 3370 was likely discovered by William Herschel, who provided it with the designation II 81. [4] His son John later designated it 750. William Herschel cataloged I 80 to NGC 3348 [4] before and II 82 to NGC 3455 after NGC 3370. [4]

The object has a surface brightness of 13 and a position angle (PA) of 140°.

On November 14, 1994, S. Van Dyk and the Leuschner Observatory Supernova Search discovered a supernova in NGC 3370 at 10h 44m 21.52s +17° 32 20.7, designated SN 1994ae. [5] SN 1994ae was a type Ia supernova, and one of the nearest and best observed since the advent of modern digital detectors. [6] The maximal light of the supernova was estimated to have occurred between November 30 and December 1[ citation needed ], peaking at visual magnitude 13. [5]

Messier 100 is a grand design intermediate spiral galaxy in the southern part of the mildly northern Coma Berenices. It is one of the brightest and largest galaxies in the Virgo Cluster and is approximately 55 million light-years from our galaxy, its diameter being 107,000 light years, and being about 60% as large. It was discovered by Pierre Méchain in 1781 and 29 days later seen again and entered by Charles Messier in his catalogue "of nebulae and star clusters".. It was one of the first spiral galaxies to be discovered, and was listed as one of fourteen spiral nebulae by Lord William Parsons of Rosse in 1850. NGC 4323 and NGC 4328 are satellite galaxies of M100; the former is connected with it by a bridge of luminous matter.

The Triangulum Galaxy is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC (New General Catalogue) 598. With the D25 isophotal diameter of 18.74 kiloparsecs (61,100 light-years), the Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Andromeda Galaxy and the Milky Way.

<span class="mw-page-title-main">Messier 82</span> Starburst galaxy the constellation Ursa Major

Messier 82 (also known as NGC 3034, Cigar Galaxy or M82) is a starburst galaxy approximately 12 million light-years away in the constellation Ursa Major. It is the second-largest member of the M81 Group, with the D25 isophotal diameter of 12.52 kiloparsecs (40,800 light-years). It is about five times more luminous than the Milky Way and its central region is about one hundred times more luminous. The starburst activity is thought to have been triggered by interaction with neighboring galaxy M81. As one of the closest starburst galaxies to Earth, M82 is the prototypical example of this galaxy type. SN 2014J, a type Ia supernova, was discovered in the galaxy on 21 January 2014. In 2014, in studying M82, scientists discovered the brightest pulsar yet known, designated M82 X-2.
