Description

From Wikipedia:
Shapley 1 (Sp 1 or PLN 329+2.1) is an annular planetary nebula in the constellation of Norma with a magnitude of +12.6. As viewed from Earth, it is peculiar in that it seems to be a non-bipolar, torus-shaped planetary nebula. However, it is thought that this is due to the viewpoint of looking directly down on a binary system whose orbit is perpendicular to Earth.
Discovered in 1936 by Harlow Shapley, it is approximately 4900 light years from Earth, and is around 8700 years old.[2] At the center of the nebula is a magnitude 14 white dwarf star. It has an angular diameter of 1.1 arc minutes, which makes it about one-third (.32) of a light year across.
