The ring nebula in the constellation of Lyra is the result of a star that at the end of it's life has expelled it's outer atmosphere, this is called a planetary nebula. What is left is the core with around it an expanding ring of expelled atmosphere. M57 is one of the best examples of this kind of object.
This object is too faint to see with the naked eye but a small telescope will show the ring.
The two bright stars at the far right and left of the nebula are the two bottom stars of the constellation Lyra.
This picture is made out of a stack of 15 photos.
