| 説明 | Over 75 million light-years away in the constellation of Virgo (The Virgin) lies NGC 4981 — a spiral galaxy with a rather explosive past.NGC 4981 was discovered on 17 April 1784 by William Herschel, and subsequently documented in John Dreyer’s New General Catalogue. Over a century later, on 23 April 1968, the galaxy once again made it into the records when a Type la supernova — a stellar explosion in a binary star system — occurred within its confines: SN 1968I. SN 1968I, however, was not to be the galaxy’s only supernova. Decades later, the core collapse of a massive star led to supernova SN 2007c.More information: www.eso.org/public/images/potw1706a/Credit:ESOAcknowledgement: Flickr user Josh Barrington |
