The Owl Nebula (also known as Messier 97, M97 or NGC 3587) is a planetary nebula approximately 2,030 light years away in the constellation Ursa Major. [2] Estimated to be about 8,000 years old, [ 6 ] it is approximately circular in cross-section with a faint internal structure.

The Southern Owl Nebula (PLN 283+25.1, ESO 378-1) is a planetary nebula located in the constellation Hydra. The nebula lies at a distance of 2,030 light years from Earth. It is named so because of its resemblance to the Owl Nebula in Ursa Major. [2] The nebula is notably symmetric, round, and has a diameter of approximately four light-years ...
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 winning image of the 2009 Gemini Astronomy Contest shows a nebula at the top left of NGC 6751. [7] This 80 x 40 arcsec nebula was discovered in 1990 by Hua & Louise at the Newton focus of the Foucault telescope, 120cm in diameter at Observatoire de Haute Provence (O.H.P.) Saint Michel l'Observatoire.
IRAS 19024+0044 is a protoplanetary nebula in Aquila. Three interesting planetary nebulae lie in Aquila: NGC 6804 shows a small but bright ring. NGC 6781 bears some resemblance with the Owl Nebula in Ursa Major. It was discovered by William Herschel in 1788. [36] NGC 6751, also known as the Glowing Eye, is a planetary nebula. The nebula is ...
[5] [6] The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45,000 K and a luminosity about 100,000 times that of the Sun. [5] The star is one of the primary sources illuminating the nebula ...
NGC 457 (also designated Caldwell 13, and known as the Dragonfly Cluster, E.T. Cluster, Owl Cluster, Kachina Doll Cluster or Phi Cassiopeiae Cluster) [2] is an open star cluster in the constellation Cassiopeia.
