NGC 488 is a face-onspiral galaxy in theconstellationPisces. It was discovered byGerman-British astronomerWilliam Herschel on 13 December 1784.[3] It is at a distance of about 90 million light-years away from Earth.[4] Its diameter is estimated to be ~185,800Light Years (~52.7Kpc).[1] The galaxy has a large central bulge, and is considered a prototype galaxy with multiple spiral arms. Its arms are tightly wound. Star forming activity has been traced within the arms.[2] The nucleus of NGC 488 has been found to be chemically decoupled, being twice as metal rich as the central bulge of the galaxy. NGC 488, with the exception of its smaller companions, form the NGC 488 group; a relatively isolated galaxy group.[5]

Supernovae

[edit]

Twosupernovae have been observed in NGC 488:

  • SN 1976G (type unknown, mag. 15) was discovered byMiklós Lovas on 21 October 1976.[6][7] It was also independently discovered byPaul Wild on 23 October 1976.[8]
  • SN 2010eb (type Ia, mag. 14.7) was discovered by Libert (Berto) Monard on 12 June 2010.[9][10]
