NGC6960 on 2023-08-05_45 subs x 180 sec THE VEIL NEBULA
NGC 6960, also named, The Veil Nebula, is a cloud of
heated and ionized gas and dust in the constellation Cygnus. It constitutes the
visible portions of the Cygnus Loop, a supernova remnant, many parts of which
have acquired their own individual names and catalogue identifiers. The source
of the supernova was a star 20 times more massive than our Sun, which exploded
between 10,000 and 20,000 years ago. At the time of the explosion, the supernova
would have appeared brighter than Venus in the sky and was visible in the
daytime. The remnants have since expanded to cover an area of the sky roughly 3
degrees in diameter, or 6 times the diameter of the full Moon. The Veil Nebula
is located about 2400 light-years from the Earth.
