The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, ... The nebula was independently "discovered" ...
NGC 604 is an H II region inside the Triangulum Galaxy.It was discovered by William Herschel on September 11, 1784. It is among the largest H II regions in the Local Group of galaxies; at the galaxy's estimated distance of 2.7 million light-years, its longest diameter is roughly 1,520 light years (~460 parsecs), over 40 times the size of the visible portion of the Orion Nebula.
The Orion Nebula M42 with NGC 1980 on the right (right is south) NGC 1980 (also known as OCL 529, Collinder 72 and The Lost Jewel of Orion [6]) is a young open cluster associated with an emission nebula in the constellation Orion. It was discovered by William Herschel on 31 January 1786. [7]
In 1610, Nicolas-Claude Fabri de Peiresc discovered the Orion Nebula using a telescope. This nebula was also observed by Johann Baptist Cysat in 1618. However, the first detailed study of the Orion Nebula was not performed until 1659 by Christiaan Huygens, who also believed he was the first person to discover this nebulosity. [11]
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 ...
Messier 43 or M43, also known as De Mairan's Nebula and NGC 1982, is a star-forming nebula with a prominent H II region in the equatorial constellation of Orion.It was discovered by the French scientist Jean-Jacques d'Ortous de Mairan some time before 1731, [3] then catalogued by Charles Messier in 1769.
In 1655, Huygens discovered the first of Saturn's moons, Titan, and observed and sketched the Orion Nebula using a refracting telescope with a 43x magnification of his own design. [ 11 ] [ 10 ] Huygens succeeded in subdividing the nebula into different stars (the brighter interior now bears the name of the Huygenian region in his honour), and ...
NGC 2023 is an emission and reflection nebula in the equatorial constellation of Orion.It was discovered by the German-born astronomer William Herschel on 6 January 1785. This reflection nebula is one of the largest in the sky, [4] with a size of 10 × 10 arcminutes. [3]
