Talk:List of largest nebulae/workpage

Below is a list of the largest nebulae so far discovered, ordered by actual size (not angular diameter).

Overview
Lyman-alpha nebulae

List
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.

By physical diameter
Listed below are some notable nebulae under 500 light-years in diameter, for the purpose of comparison. All links to NED are available, except for the Milky Way, which is linked to the relevant paper detailing its size.
