NGC 4900

Coordinates:Sky map13h 00m 39.2568s, +02° 30′ 02.687″
From Wikipedia, the free encyclopedia
Barred spiral galaxy in the constellation Virgo
NGC 4900
A spiral galaxy seen face-on. Broken spiral arms made of blue patches of stars and thin strands of dark dust swirl around the galaxy’s centre, forming a broad, circular disc. An extended circular halo surrounds the disc. The centre is a brightly-glowing, stubby bar-shaped area in a pale yellow colour. A bright star in our own galaxy, with long cross-shaped diffraction spikes, is visible atop the distant galaxy.

It was discovered byWilliam Herschel on April 30, 1786.[2] It is a member of theNGC 4753 Group of galaxies, which is a member of theVirgo II Groups, a series of galaxies andgalaxy clusters strung out from the southern edge of theVirgo Supercluster.[3]

Onesupernova has been observed in NGC 4900: SN 1999br (Type II, mag. 17.5) was discovered by theLick Observatory Supernova Search (LOSS) on 12 April 1999.[4][5]
