Ring Nebula. Ring Nebula (M57, NGC 6720). This object consists of an expanding shell of material ejected from a star around 1600 years ago. It is about 2300 light years away, in the constellation of Lyra. This early photograph (an albumen silver print from a glass negative) was obtained in around 1885 by French astronomers Paul and Prosper Henry from the Paris Observatory. The two brothers had developed a photographic telescope that was able to track objects in the night sky for as long as an hour.
