NGC 4647 is a spiral galaxy located about 63 million light-years away[2] in the constellation of Virgo.[3] It was discovered by astronomer William Herschel on March 15, 1784.[3] NGC 4647 is listed along with Messier 60 as being part of a pair of galaxies called Arp 116.[4][5] The galaxy is a member of the Virgo Cluster.[2][6]

Physical characteristics

Interaction with Messier 60

In optical images, the two galaxies disks overlap. This has suggesting an ongoing interaction, however images do not reveal any signs of star formation which would have been caused by a tidal interaction between the two galaxies. Recent studies of Hubble images made in 2012 of the two galaxies indicate that tidal interactions between the two have just begun.[7]

SN1979A

On January 25, 1979 a Type-1 supernova was discovered in NGC 4647. [8][9]
