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.
A labeled map of the Orion molecular cloud, with the images taken by IRAS and various telescopes that mapped CO in this part of the sky. The following is a list of notable regions within the larger complex: Orion A molecular cloud The Orion Nebula, also known as M42 (part of Orion's Sword) M43, which is part of the Orion Nebula
Messier 43 or M43, also known as De Mairan's Nebula and NGC 1982, is a star-forming nebula with a prominent H II region in the equatorial constellation of Orion. It was discovered by the French scientist Jean-Jacques d'Ortous de Mairan some time before 1731, [ 3 ] then catalogued by Charles Messier in 1769.
Scientists have announced the discovery of structures like layering and potential impact craters which had been hidden under Mars’ polar ice caps. New 3-D map of Mars' ice caps reveal hidden ...
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 ...
Burnham's Celestial Handbook lists the entire nebula as 2174/2175 and does not mention the star cluster. [1] 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.

The M78 cloud contains a cluster of stars that is visible in the infrared. [2] Due to gravity, the molecular gas in the nebula has fragmented into a hierarchy of clumps, [2] whose cores have masses ranging from 0.3 M ☉ to 5 M ☉. [6] About 45 variable stars of the T Tauri type, [7] young stars still in the process of formation, are members ...
