NGC 6995

The Veil Nebula, also known as the Cygnus Loop or the Network Nebula, is a diffuse nebula in the constellation Cygnus. It is a vast and relatively faint supernova remnant. The star exploded approximately 5,000–8,000 years ago, and over that time the nebula has expanded to cover an area of 3 degrees in the sky. Its distance is estimated to be 2,400 light-years, and it was discovered on September 5, 1784, by William Herschel. The nebula is so large that its parts are considered separate nebulae and have their own names.

NGC 6960 – the western arc, which includes the star 52 Cyg – is the "Witch's Broom" nebula.
NGC 6979 – the triangular nebula in the northwest part of the loop – is "Pickering's Triangle."
NGC 6992 – the northern part of the eastern arc – is the "Sword."
NGC 6995 – the southern part of the eastern arc (together with NGC 6992, it forms the "Network" nebula).
NGC 6974 and NGC 6979 – a pair of nebula fragments in the northern part of the Loop (between the triangle and the eastern arc).
