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]
Theta 1 C is itself a binary of two massive stars, C1 and C2, plus a very close fainter companion apparently escaping the system. [9] Theta 1 Orionis C1 is responsible for generating most of the ultraviolet light that is slowly ionizing (and perhaps photoevaporating) the Orion Nebula. This UV light is also the primary cause of the glow that ...
The Trapezium or Orion Trapezium Cluster, also known by its Bayer designation of Theta 1 Orionis (θ 1 Orionis), is a tight open cluster of stars in the heart of the Orion Nebula, in the constellation of Orion. It was discovered by Galileo Galilei. On 4 February 1617 he sketched three of the stars (A, C and D), but missed the surrounding ...
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
DALLAS (AP) — NASA’s Webb Space Telescope has revealed the sharpest images yet of a portion of a horse-shaped nebula, showing the “mane” in finer detail. The Horsehead Nebula, in the constellation Orion, is 1,300 light-years away. A light-year is nearly 6 trillion miles (9.7 trillion kilometers).
