Most nebulae are of vast size; some are hundreds of light-years in diameter. A nebula that is visible to the human eye from Earth would appear larger, but no brighter, from close by. [ 6 ] The Orion Nebula , the brightest nebula in the sky and occupying an area twice the angular diameter of the full Moon , can be viewed with the naked eye but ...
List of the largest nebulae Image Nebula Maximum dimension (in light-years/parsecs) Type Notes NGC 262 Halo Cloud 1,300,000 ly (400,000 pc) [1] H I region: Spiral nebula surrounding NGC 262, which is one of the largest known galaxies. Leo Ring: 650,000 ly (200,000 pc) [2] HVC: A large ring of cold gas that formed from a collision of two ...
The M42 nebula is estimated to be 24 light-years across (so its apparent size from Earth is approximately 1 degree). It has a mass of about 2,000 times that of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula. [7]
The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding , most likely before 1824, this object is one of the closest of all the bright planetary nebulae to Earth. [ 3 ]
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. [4] ... The distance estimates affect also the estimates of size and age.)
NGC 7027 is unusually small, measuring only 0.2 by 0.1 light-years, whereas the typical size for a planetary nebula is 1 light-year. [4] It is fairly young, at about 600 years old. [ 12 ] It has a very complex shape, consisting of an elliptical region of ionized gas [ 13 ] and an equatorial belt [ 14 ] within a massive neutral cloud. [ 15 ]
The Cosmic Cliffs at the edge of NGC 3324, one of the first images taken by the James Webb Space Telescope. The Carina Nebula [7] or Eta Carinae Nebula [8] (catalogued as NGC 3372; also known as the Great Carina Nebula [9]) is a large, complex area of bright and dark nebulosity in the constellation Carina, located in the Carina–Sagittarius Arm of the Milky Way galaxy.
The Horsehead Nebula (also known as Barnard 33 or B33) is a small dark nebula in the constellation Orion. [2] The nebula is located just to the south of Alnitak , the easternmost star of Orion's Belt , and is part of the much larger Orion molecular cloud complex .
