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.
JWST NIRCam observed the central part of the Orion Nebula, including proplyd 114-426. This observation found a dip at 3 μm, which is seen as evidence of water ice . The grain size was estimated to be smaller than 0.25 to 5 μm and the dust+ice mass of the disk was estimated to be 0.46 M E in the silhouette region. [ 3 ]
The proplyds in the Orion Nebula and other star-forming regions represent proto-planetary disks around low-mass stars being externally photoevaporated. These low-mass proplyds are usually found within 0.3 parsec (60,000 astronomical units ) of the massive OB star and the dusty proplyds have tails with a length of 0.1 to 0.2 parsec (20,000 to ...
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.
NGC281, popularly the 'Pacman Nebula', imaged from a suburban location using a 130mm amateur telescope and a DSLR camera. Since most people live in urban areas , equipment often needs to be portable so that it can be taken far away from the lights of major cities or towns to avoid urban light pollution .
