  What it is

At a distance of about 1,500 light years, the nebula is a large supernova remnant from a massive star. It is an expanding cloud resulting from the explosion of the star that occurred ~ 5,000 years ago. It is now about 70 light years across and from Earth this is an apparent size of about 6 Moon diameters in the sky.
