NGC 1788 is a reflection nebula in the constellation of Orion. It is rather sharply defined on its southwest perimeter where it is flanked by the dark nebula known as LDN 1616 (or Lynds 1616). LDN 1616 is apparently part of NGC 1788. The brightest involved star is 10th magnitude and lies in the northwest sector.
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 ...
Orion's Belt or The Belt of Orion is an asterism within the constellation. It consists of the three bright stars Zeta (Alnitak), Epsilon (Alnilam), and Delta (Mintaka). Alnitak is around 800 light years away from earth and is 100,000 times more luminous than the Sun and shines with magnitude 1.8; much of its radiation is in the ultraviolet ...
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 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 ...
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.
Map showing the location of NGC 2169. NGC 2169 is an open cluster in the Orion constellation. It was possibly discovered by Giovanni Batista Hodierna before 1654 and discovered by William Herschel on October 15, 1784. [1] NGC 2169 is at a distance of about 3,600 light years away from Earth.
