  • About the Veil Nebula:

    The Veil Nebula is what is left after a red giant star went supernova some 5000 years ago.  The star threw off a large amount of matter that has been speeding away from the star at about 70 km/second.  Shown above is the eastern portion of a large circle of gas.  The entire Veil Nebula covers an area over five times that of the full moon.
