Latest Orion Molecular Cloud Complex Stories
The European Southern Observatory (ESO) has released a new image of the constellation of Orion showing part of the Orion Molecular Cloud.
Dense clouds of cosmic gas and dust in space are the birthplaces of new stars. When viewing these in visible light, the dust is dark and obscuring, which helps to hide the stars.
The cosmos is full of outstanding imagery, and a new image from NASA's Wide-field Infrared Survey Explorer, or WISE, has shot back another outstanding image back to Earth.
Astronomers have completed the most comprehensive census of the star formation surrounding the Orion Nebula.
Nebula -- in astronomy, observed manifestation of a collection of highly rarefied gas and dust in interstellar space. Prior to the 1960s this term was also applied to bodies later discovered to be galaxies, e.g., the so-called Great Nebula in the constellation Andromeda. In 1864, William Huggins confirmed William Herschel's conclusion that nebulae are not swarms of stars by determining that the spectra of nebulae are made of bright lines characteristic of radiating gases. Diffuse...
Orion Nebula -- Discovered 1610 by Nicholas-Claude Fabri de Peiresc. Located at a distance of about 1,600 (or perhaps 1,500) light years, the Orion Nebula is the brightest diffuse nebula in the sky, visible to the naked eye, and rewarding in telescopes of every size, from the smallest glasses to the greatest Earth-bound observatories and the Hubble Space Telescope. It is the main part of a much larger cloud of gas and dust which extends over 10 degrees well over half the constellation...
