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 ...

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.
The optical channel has a field of view of 164 by 164 arcsec (2.7 by 2.7 arcminute, about 8.5% of the diameter of the full moon as seen from Earth) with 0.04 arcsec pixels. This view is comparable to the Wide Field and Planetary Camera 2 and is slightly smaller than that of the Advanced Camera for Surveys .
Hubble Space Telescope image of the nebula M1-67 and WR 124 at its center. WR 124 is surrounded by an intensely hot nebula formed from the star's extreme stellar wind. [ 9 ] The nebula M1-67 is expanding at a rate of over 150,000 km/h (93,000 mph) and is nearly 6 light-years across, leading to the dynamical age of 20,000 years.
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.
