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]
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.

A starchart of the Orion Nebula Optical images reveal clouds of gas and dust in the Orion Nebula; an infrared image (right) reveals the new stars shining within. The entirety of the Orion Nebula extends across a 1° region of the sky, and includes neutral clouds of gas and dust, associations of stars, ionized volumes of gas, and reflection nebulae.
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 ...
