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.
Hubble discovery images of Proplyd 114-426. The disk is one of the largest in the Orion Nebula. Initially the diameter was measured to be 2.3 arcseconds or 1012 AU. The dust mass of the disk was estimated to be 2.9 x 10 28 grams (4.6 M E) and the total (gas+dust) mass was estimated to be 4.34 x 10 30 g (2.29 M J). [6]

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 ...
NASA’s Webb Space Telescope has revealed the sharpest images yet of a portion of a horse-shaped nebula, showing the “mane” in finer detail. The Horsehead Nebula, in the constellation Orion ...
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 ...
English: Photo taken by Rogelio Bernal Andreo in October 2010 of the Orion constellation showing the surrounding nebulas of the Orion Molecular Cloud complex. Also captured is the red supergiant Betelgeuse (top left) and the famous belt of Orion composed of the OB stars Alnitak, Alnilam and Mintaka. To the bottom right can be found the star Rigel.
NGC 2174 (also known as Monkey Head Nebula) is an H II [1] emission nebula located in the constellation Orion and is associated with the open star cluster NGC 2175. [1] It was discovered on 6 February 1877 by French astronomer Édouard Stephan. [2] It is thought to be located about 6,400 light-years away from Earth.
