NGC 6960 (also called the Western Veil Nebula) is a cloud of hot ionized gas and dust in the constellation Cygnus. It forms the western edge of the Cygnus Loop, a supernova remnant, and is about 1500 light years away. NGC 6960 is the portion at the top center. The triangular portion at the lower left is called Pickering's Triangle. It was named after Harvard Professor Edward Pickering but was discovered by his assistant, Williamina Fleming, in 1904.
