The '''Footprint nebula''' (Minkowski 92, M1-92, IRAS 19343+2926) is a bipolar [[planetary nebula]] in the [[constellation]] of [[Cygnus]], the swan.<ref>{{cite web|url=http://annesastronomynews.com/photo-gallery-ii/nebulae-clouds/minkowskis-footprint/|title=Minkowski’s Footprint, a protoplanetary nebula in Cygnus|accessdate=2019-09-27|publisher=annesastronomynews.com|date=2014-07-16}}</ref> Also known as Minkowski's Footprint, the nebula is composed of two large [[onion]]-like structures. There is a [[star]] situated at the centre of the nebula.
