NGC 4900
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. NGC 4900 imaged by the Hubble Space Telescope | |

NGC 4900 is a barred spiral galaxy in the constellation Virgo. It was discovered by William Herschel on April 30, 1786.[2] It is a member of the NGC 4753 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster.[3]
One supernova has been observed in NGC 4900: SN 1999br (Type II, mag. 17.5) was discovered by the Lick Observatory Supernova Search (LOSS) on 12 April 1999.[4] [5]
