Abell 33 (Also called A33 or the Diamond ring nebula) is a faint spherical planetary nebula located 2700 light years away in the constellation of Hydra. It lies just behind the star HD 83535 which has no relation to the nebula. [1] The star HD 83535 is also responsible for the " diamond ring" effect seen in the photograph.
The nebula gets its coloration from the Olll emissions ( doubly ionized oxygen). The nebula is faint making it difficult to be seen using a telescope. The spherical shape of Abell 33 is mainly caused by its central star not having much of a spin. [2] The nebula shares similar morphology to another nebula with the same spherical shape, the Owl Nebula ( M 97) but is much darker than the owl nebula. [3]
