The Propeller Nebula (DWB 111/9) in Cygnus may look as if it was produced by a rotating object flinging material into space. But in fact the object has no central star. A 2021 study found the region is likely excited by the star WR 140, which lies about 50′ away. This Hubble palette image was taken with dual-band Hα/OIII and SII filters over 19.1 hours with an 8-inch scope.
