The “Witch’s Broom”, aka NGC6960 is a small part of the Veil nebula supernova remnant. A massive star exploded ~9000 years ago and shone brightly for only a few days. Today this large (36 times the area of the full Moon), but dim remnant is only visible using a telescope and sensitive electronics. The “Witch’s Broom” portion of the Veil spans about 35 light-years and is ~1,500 light-years distant in the constellation Cygnus. The bright star at its center is “52 Cygni”. Although this star appears very bright in the image it is only visible with the unaided eye from a dark location.
