Galaxy in the constellation Coma Berenices
NGC 4414 , also known as theDusty Spiral Galaxy ,[ 3] unbarred spiral galaxy about 62 millionlight-years away in theconstellation Coma Berenices . It was discovered byGerman-British astronomerWilliam Herschel on 13 March 1785.[ 4]
NGC 4414 is aflocculent spiral galaxy , with short segments of spiral structure but without the dramatic well-defined spiral arms of agrand design spiral .
The galaxy was imaged by theHubble Space Telescope in 1995, as part of the HST's main mission to determine the distance to galaxies, and again in 1999 as part of theHubble Heritage project . It has been part of an ongoing effort to study itsCepheid variable stars. The outer arms appear blue due to the continuing formation ofyoung stars and include a possibleluminous blue variable with anabsolute magnitude of −10.[ 5]
NGC 4414 is also an isolated galaxy without signs of pastinteractions with other galaxies [ 6] starburst galaxy shows a high density and richness of gas – bothatomic andmolecular , with the former extending far beyond its optical disk.[ 7]
NGC 4414 is a member of theComa I Group , a group of galaxies lying physically close to theVirgo Cluster .[ 8] [ 9]
Foursupernovae have been observed in NGC 4414:
SN 1974G (Type I , mag. 13) was discovered by Miss W. Burgat on 20 April 1974.[ 10] [ 11] SN 2013df (Type IIb , mag. 14.4) was discovered by the Italian Supernovae Search Project on 7 June 2013.[ 12] [ 13] SN 2021J (Type Ia , mag. 12) was discovered by theAutomatic Learning for the Rapid Classification of Events (ALeRCE) on 1 January 2021.[ 14] SN 2023hlf (Type II , mag. 17.8) was discovered by theZwicky Transient Facility on 1 May 2023.[ 15] ^a b c d e f g h "NASA/IPAC Extragalactic Database" .Results for NGC 4414 .
