List of largest nebulae

From EverybodyWiki Bios & Wiki


NGC 604, one of largest nebulae (H II region) is localed in the Triangulum Galaxy (viewed by the Hubble Space Telescope).

Below is a list of the largest nebulae so far discovered, ordered by size. This list is prone to change because of inconsistencies between studies, their great distances from our stellar neighbourhood, and constant development of technology and engineering. Nebulae's boundaries are also undefined, and is also prone to change. Lastly, scientists are still defining the parameters and defining features of nebulae. Because of all these scientific inconsistencies, this list might be unreliable.

Notes[edit]

  1. ↑ distance × sin( diameter_angle ) = 1,895 ly
  2. ↑ distance × sin( diameter_angle ) = 1,520 ly
  3. ↑ Those measuraments are based on an apparent diameter of 480 arcminutes (') plus an assumed distance of 1.5 kpc and the current distance of VY CMa which is about 1.17 kpc as the nebula is sometimes found to have the same distance as VY CMa.
