Brightest Nebulae in the Night Sky | Pictures ... - AstroBackyard
The Carina Nebula is one of the brightest nebulae in the night sky. It is a massive star-forming region that measures over 300 light-years across, displaying beautifully bright and dark nebulosity. This Southern Hemisphere target is four times larger than the Orion Nebula, a popular Northern Hemisphere deep-sky target.
Nebula - Wikipedia
A nebula (Latin for 'cloud, fog'; [1] pl.: nebulae, nebulæ, or nebulas [2] [3] [4] [5]) is a distinct luminescent part of interstellar medium, which can consist of ionized, neutral, or molecular hydrogen and also cosmic dust. Nebulae are often star-forming regions, such as in the Pillars of Creation in the Eagle Nebula.
Best & Brightest Nebulae | Night Sky Stargazing | GO ASTRONOMY
For nebulae, "brightness" is a function of magnitude, surface brightness, and apparent size. This is because apparent magnitude applies most accurately to brightness for point objects like stars. Nebulae have an apparent size in the night sky, so their magnitude is "spread out" across it.

2024年9月16日 · The Lynds' Catalog of Bright Nebulae lists the coordinates of the center of the cloud, the dimensions of the nebulae as measured on the photograph on which it appeared at its brightest, the area of nebulosity in square degrees, color as compared between the blue and red Palomar plates, a brightness index on a scale from 1 to 6, an ...
Lynds' Catalogue of Bright Nebulae - Wikipedia
Lynds' Catalogue of Bright Nebulae (abbreviation: LBN) is an astronomical catalogue of bright nebulae. Objects listed in the catalogue are numbered with the prefix LBN (not to be confused with LDN, or Lynds' Catalogue of Dark Nebulae), though, many entries also have other designations, for example, LBN 974, the Orion Nebula is also known as M ...

Orion Nebula - Wikipedia
The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion, [b] and is known as the middle "star" in the "sword" of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky with an apparent magnitude of 4.0.
Bright Nebula Observing Program - Astronomical League
Bright nebulae, also called diffuse or Galactic nebulae, occur in two main classes depending on their source of illumination: emission and reflection, although they occasionally are a combination of the two (R+E). Much less common is a third type …
