As the Orion Nebula was the 42nd object in his list, it became identified as M42. Henry Draper's 1880 photograph of the Orion Nebula, the first ever taken. One of Andrew Ainslie Common's 1883 photographs of the Orion Nebula, the first to show that a long exposure could record new stars and nebulae invisible to the human eye.
The Trapezium or Orion Trapezium Cluster, also known by its Bayer designation of Theta 1 Orionis (θ 1 Orionis), is a tight open cluster of stars in the heart of the Orion Nebula, in the constellation of Orion. It was discovered by Galileo Galilei. On 4 February 1617 he sketched three of the stars (A, C and D), but missed the surrounding ...
JWST NIRCam observed the central part of the Orion Nebula, including proplyd 114-426. This observation found a dip at 3 μm, which is seen as evidence of water ice . The grain size was estimated to be smaller than 0.25 to 5 μm and the dust+ice mass of the disk was estimated to be 0.46 M E in the silhouette region. [ 3 ]
The NGC Project (working from the original descriptive notes) assigns NGC 2174 to the prominent knot at J2000 06 h 09 m 23.7 s, +20° 39′ 34″ and NGC 2175 to the entire nebula, and by extension to the star cluster. [2] Simbad uses NGC 2174 for the nebula and NGC 2175 for the star cluster. [3] [4] NGC 2175, LRGBHa image with 17" PlaneWave ...
Theta 1 Orionis C (θ 1 Orionis C) is a member of the Trapezium open cluster that lies within the Orion Nebula. The star C is the most massive of the four bright stars at the heart of the cluster. It is an O class blue main sequence star with a B-type main sequence companion.
NGC 1981 (also known as OCL 525) is an open cluster which is located in the constellation Orion. It was discovered by John Herschel on 4 January 1827. Its apparent magnitude is 4.2 [3] and its size is 28.00 arc minutes. It lies to the north of the Orion Nebula, separated from it by the Sh2-279 region containing NGC 1973, 1975, and 1977.
The Becklin–Neugebauer Object (BN) is an object visible only in the infrared in the Orion molecular cloud 1 (OMC1). It was discovered in 1967 by Eric Becklin and Gerry Neugebauer during their near-infrared survey of the Orion Nebula. [4]
Messier 78 or M78, also known as NGC 2068, is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of comet-like objects that same year. [4] M78 is the brightest diffuse reflection nebula of a group of nebulae that includes NGC 2064, NGC 2067 and NGC 2071.
