A starchart of the Orion Nebula Optical images reveal clouds of gas and dust in the Orion Nebula; an infrared image (right) reveals the new stars shining within. The entirety of the Orion Nebula extends across a 1° region of the sky, and includes neutral clouds of gas and dust, associations of stars, ionized volumes of gas, and reflection nebulae.
Hubble discovery images of Proplyd 114-426. The disk is one of the largest in the Orion Nebula. Initially the diameter was measured to be 2.3 arcseconds or 1012 AU. The dust mass of the disk was estimated to be 2.9 x 10 28 grams (4.6 M E) and the total (gas+dust) mass was estimated to be 4.34 x 10 30 g (2.29 M J). [6]
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
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 ...
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 ...
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 ...
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. [2] Simbad uses NGC 2174 for the nebula and NGC 2175 for the star cluster. [3] [4] NGC 2175, LRGBHa image with 17" PlaneWave ...
