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.
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 Orion A cloud has a mass in the order of 10 5 M ☉. [7] The stars in Orion A do not have the same distance to us. The "head" of the cloud, which also contains the Orion Nebula is about 1300 light-years (400 parsecs) away from the Sun. The "tail" however is up to 1530 light-years (470 parsecs) away from the Sun.
LDN 1641 or Lynds 1641 is a dark cloud in the constellation Orion. It encompasses a large part of the Orion A molecular cloud in the Orion molecular cloud complex, which is the closest giant molecular cloud to earth. At its northern end it is connected to the Orion Nebula and at its southern end it is connected to the dark cloud LDN 1647. [3]
You can also find a nebula in Orion. Look below Orion’s Belt for three fainter stars in a rough line. With the naked eye, the second brightest “star” may look a little fuzzy around the edges.
One of Andrew Ainslie Common's 1883 photographs of the same nebula, the first to show that a long exposure could record stars and nebulae invisible to the human eye. Astronomical photography did not become a serious research tool until the late 19th century, with the introduction of dry plate photography. [ 10 ]
Map showing the Orion OB1 association, which contains the blue supergiants of Orion's Belt and the Orion Nebula. Betelgeuse is believed to be a runaway star that was ejected from the Orion OB1 association. The kinematics of Betelgeuse are complex. The age of Class M supergiants with an initial mass of 20 M ☉ is roughly 10 million years.
If the Tarantula Nebula were as close to Earth as the Orion Nebula, it would shine about as brightly as the full moon in the night sky. The supernova SN 1987A occurred in the outskirts of the Tarantula Nebula. [32] Another giant H II region—NGC 604 is located in M33 spiral galaxy, which is at 817 kpc (2.66 million light years).
