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 maximum angular separation of the Earth and Moon varies considerably according to the relative distance between the Earth and Mars: it is about 25′ when Earth is closest to Mars (near inferior conjunction) but only about 3.5′ when the Earth is farthest from Mars (near superior conjunction). For comparison, the apparent diameter of the ...
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.
The constellation Orion will also be visible throughout the night, just to the right of Jupiter, the moon and Mars. In the middle of the constellation, onlookers can spot Orion's Belt, a line of ...

ORLANDO, Fla. — NASA officials said the Orion spacecraft traveled to its farthest distance from Earth on Monday, two days after breaking a record set by Apollo 13. On Saturday, Orion, which ...
Barnard's Loop (catalogue designation Sh 2-276) is an emission nebula in the constellation of Orion. It is part of the Orion molecular cloud complex which also contains the dark Horsehead and bright Orion nebulae. The loop takes the form of a large arc centered approximately on the Orion Nebula. The stars within the Orion Nebula are believed to ...
Another fairly bright nebula in Orion is NGC 1999, also close to the Great Orion Nebula. It has an integrated magnitude of 10.5 and is 1500 light-years from Earth. The variable star V380 Orionis is embedded in NGC 1999. [21] Another famous nebula is IC 434, the Horsehead Nebula, near ζ Orionis. It contains a dark dust cloud whose shape gives ...
