description Diamond Ring Nebula (Abell 33) Overview
Abell 33, sometimes called the Diamond Ring Nebula, is a planetary nebula located in the constellation Hydra. The nebula appears almost perfectly spherical and is illuminated by a central white dwarf, the remnant of the original star. The "diamond ring" effect arises from the chance alignment of a foreground star near the nebula's rim, creating an optical illusion visible in long-exposure astrophotography.
