'''SN 1986G''' was a [[supernova]] that was observed on May 3, 1986 by [[Robert Evans (astronomer)|Robert Evans]].  Its host [[galaxy]], [[Centaurus A]], is about [[1 E22 m|15 million]] [[light-year]]s away in the [[constellation]] [[Centaurus]]. Since Centaurus A is about 15 million light-years away from us, this supernova happened 15 million years ago.{{cite-needed|date=September 2023}}

SN 1986G was a bright blue-green [[star]] in the middle of the left part of the dust belt of Centaurus A. The blue-green color occurs because David Malin could take the red plate used in this composite image only one year after the supernova occurred, and it had faded away at that time.
