| Abell 33 - The Diamond Ring Nebula The Diamond Ring Nebula is a very faint spherical planetary nebula in the constellation Hydra. It gets its bluish color from doubly ionized oxygen. The star in the lower-right corner of the nebula is not associated with the nebula, but actually considerably closer to us. Since the nebula is so faint, one can only see it with a timed exposure. It lies about 2700 light-years away from us. Image processed by Ron Yelton, original data from Telescope Live |
Gamma Cygni Nebula The image of this nebula is just part of the nebulosity that surrounds the star Navi, in the constellation Cassiopeia. The hot stars embedded in the nebulosity excite (heat) the surrounding gasses enough that the gasses begin to glow. That makes most of the nebula an emission nebula. This one is about 1500 light-years away. Image processed by Ron Yelton, original data from Telescope Live |
