Resembling a tulip, Sharpless 101 is an emission nebula in Cygnus about 6000 ly away. To the right of it is Cygnus X-1, a very strong X-ray source and widely believed to be a Black Hole candidate. The visible star is SAO69181 and orbits the black hole. The in-falling matter from the star is heated to millions of degrees, producing X-rays.
