|This journey begins with the familiar sight of the bright constellation Orion, where we see The Hunter on the right and the bright star Sirius in the lower left. Then we zoom in the region of the sword of the Hunter, which shows the Orion Nebula, also known as Messier 42, a vast stellar nursery located about 1350 light years from Earth. The small nebula located on the left above is the M43 nebula. Then we move to the view of the Earth VISTA telescope at Paranal, observing in the infrared part of the electromagnetic spectrum. VISTA takes us in a huge zoom which allows us to admire the splendor of the Orion Nebula and its surroundings in a single image. With its infrared vision telescope that can peer deep diffuse and dusty regions that are normally hidden. It reveals us here, beautiful young stars are very active lurking in the dense clouds of gas and dust. The observations in the infrared range, allowing astronomers to peer into the cold universe.|
The glowing gas of M42 surrounds hot young stars on the edge of a huge molecular cloud. At the heart of the nebula, four blue stars forming a trapezium illuminate long-range diffuse matter dispersed in space. The atoms absorb the stellar light and re-emit in accordance with their own colors, that of oxygen is green, those of hydrogen and nitrogen is red. Radio astronomical observations reveal that the Orion Nebula is only a small part of the large opaque cloud of Orion. Of the contraction of this cloud were born Trapezium stars, and a group of proto-stellar nebulae behind the Orion Nebula. The Orion nebula was discovered in 1610 by Nicolas-Claude Fabri de Peiresc who was apparently the first to notice its nebulous appearance. Ptolemy, Tycho Brahe and Johann Bayer identified the stars in the center of the nebula, as one big star.
Video: Dazzling journey into the Orion Nebula. This trip just a minute, takes us on a deep and dramatic zoom of the Orion Nebula. We are down to the center of the nebula, in dense clouds of gas and dust. These images were taken from the Atacama Desert (Chile) by the Vista telescope (infrared). The observations in the infrared allows astronomers to peer into the cold universe and see the cooler regions. The Orion Nebula also known as M42 or NGC 1976 is an emission / reflection nebula in the heart of the constellation Orion. This is one of the most beautiful sights of heaven. The Orion Nebula is the main part of a cloud of gas and dust called the "cloud of Orion ." The Orion cloud occupies nearly half of the constellation, in this cloud found Barnard's Loop and the famous Nebula Horsehead. The Orion nebula has a size of about 33 light-years. Credit: ESO/J.
