The Western Veil Nebula is a supernova remnant in the constellation Cygnus and is a compnent of the much larger Cygnus loop. The ionized gases visible in this image originated from the supernova of a star at least 20 times larger than our sun. It is estimated that at the time of supernova, it would have been visible during daylight hours on Earth and would have had an apparent brightness similar to Venus during dark hours. Careful examination of the image will reveal delicate features from the ionized oxygen (blue) and hydrogen (red).
