NGC 4527 is a spiral galaxy in the constellation Virgo. It was discovered by German-British astronomer William Herschel on 23 February 1784.[2]

NGC 4527 is a member of the M61 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]

Characteristics

NGC 4527 is an intermediate spiral galaxy similar to the Andromeda Galaxy[4] and is located at a distance not well determined, but usually is considered to be an outlying member of the Virgo Cluster of galaxies,[5] being placed within the subcluster known as S Cloud.[6]

Unlike the Andromeda Galaxy, NGC 4527 is also a starburst galaxy, with 2.5 billion solar masses of molecular hydrogen concentrated within its innermost regions.[7] However said starburst is still weak and seems to be on its earliest phases.[7]

Supernovae

Three supernovae have been observed in NGC 4527:
