Discussing the location of the Orion Nebula, what is seen within the star-formation region, and the effects of interstellar winds in shaping the nebula The constellation of Orion with the Orion Nebula (lower middle) The Orion Nebula is visible with the naked eye even from areas affected by light pollution. It is seen as the middle "star" in the ...
It was discovered in 1967 by Eric Becklin and Gerry Neugebauer during their near-infrared survey of the Orion Nebula. [4] A faint glow around the center-most stars can be observed in the visible light spectrum, especially with the aid of a telescope. The BN Object is thought to be an intermediate-mass protostar.
IC 2118 (also known as Witch Head Nebula due to its shape) is an extremely faint reflection nebula believed to be an ancient supernova remnant or gas cloud illuminated by nearby supergiant star Rigel in the constellation of Orion. The nebula lies in the Eridanus Constellation, [1] about 900 light-years from Earth. The nature of the dust ...
Visible to the naked eye in all parts of the sky in both the northern and southern hemisphere, all that is needed to spot the display is a clear sky and a safe spot away from street lights and ...
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 ...
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 ...
The Kleinmann–Low Nebula is at the heart of the Orion Nebula, and is the most active star-forming region in it. Because of the thick dust surrounding it, it is observed primarily with infrared light, since visible light cannot pass through it. [2] Hot stellar winds circulate off large, young, stars in Orion's nebula and heat the surrounding gas.
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.
