The Lambda Orionis ring is a large molecular ring, centered around Lambda Orioinis . The nebula lies at an approximate distance of 1,350 light years from Earth and has an apparent magnitude of 2. The system is moving closer to the Sun with a radial velocity of −12 kms. The Meissa Ring is of interest to astronomers because it contains clusters of young stars and proto-stars, or forming stars, embedded within the clouds. Star-formation is still continuing in regions of the ring. [NASA/JPL/Caltech/UCLA] GW Ori is a system of three stars that are gravitationally bound. The ring shows its H II region status in the infrared — this image includes the very bright source of infrared and near-infrared Betelgeuse, therefore blue-white when shown converted to visible light. The name Betelgeuse is actually a corruption of the original Arabic phrase "Yad al-Jauza'," meaning "hand of the giant one." Your browser or your browser's settings are not supported.

It is a molecular cloud and HII region, also known as Lambda Orionis Ring, which lies in northern region of Orion's molecular cloud complex (OMCC), in Orion constellation. A wide angle view pointing deep into the region of the sky near Orion constellation, reveals the faint dark nebulosity which seems to spread between Barnard´s Loop nebula, located on the left edge, Lambda Orionis nebula, as seen in the bottom, and Rosette nebula, shinning in to top right corner. The results of a new CO (J=1->0) survey of the ring of molecular clouds around the H ii region Sh-2-264 and the lambda -Orionis OB-association are presented. The ring of molecular clouds surrounding Lambda Orionis can best be explained by a supernova about one million years ago. At the center is the star Lambda Orionis (the red one in the middle of the ring), a supergiant that, along with other massive stars, is warming … Sh 2-264 is ionised by the O8 III star Lambda Orionis, and to a lesser extent, the 11 B stars near to it. The Lambda Orionis ring is a large molecular ring, centered around Lambda Orioinis . It has a small nebulous cloud more geared towards the near-infrared than other parts of the neighbouring ionized regions across the Ring. Barnard 30 is the bright knob of gas and dust in the top center part of the image. The broad nebula shown is not visible unaided, with binoculars or small amateur telescopes. Barnard 35 appears as a hook extending towards the center of the ring just above and to the right of the star Betelgeuse. It becomes clear in long-exposure photographs, such as in the first illustration on this page. The star HD 34989 is surrounded by material that is part of the Lambda Orionis Ring. Es una nube molecular y región HII, también conocida como el Anillo de Lambda Orionis, que se encuentra en la región norte del complejo de nubes moleculares de Orión (OMCC), en la constelación de Orión. Blue and cyan represent 3.4- and 4.6-microns, primarily light emitted by hot stars. It was suggested that this ring formed after a supernova happened inside the central star-forming region that once surrounded the Lambda Orionis Cluster, dispersing the material into the ring seen today. The ring can perhaps best be explained by a supernova very close to the O8 III multiple giant Lambda Orionis about 1 million years ago. Sharpless 264, also known as the Lambda Orionis Ring, is a molecular cloud and H II region, which can be seen in the northern region of the Orion Molecular Cloud Complex (OMCC), in the constellation of Orion.

The images of this region were taken with the Spitzer Space Telescope. HD 34989 is a Blue-white main sequence star, visible magnified only, between Lambda Ori. The molecular ring associated with the Lambda Orionis cluster, as seen by NASA’s Wide-Field Infrared Survey Explorer. It is a faint naked eye star. The OMCC is one of the best-known star formation regions and the closest sector of the Milky Way to our Solar System where high-mass stars are born. It has an estimated radius about 887 to 955 times that of the Sun and is one of the largest stars that can be seen without binoculars. Also known as SH 2-264, the Lambda Orionis molecular ring is sometimes called the Meissa ring. It was suggested that this ring formed after a supernova happened inside the central star-forming region that once surrounded the Lambda Orionis Cluster, dispersing the material into the ring seen today. "In the featured long-exposure image, thousands of stars in our Milky Way Galaxy can be seen in the background behind Betelgeuse, as well as dark dust from the Orion Molecular Cloud, and some red-glowing emission from hydrogen gas on the outskirts of the more distant Lambda Orionis Ring. Star-formation is still continuing in regions of the ring. The bright reddish object seen to in the middle right part of the image is the star HR 1763, which is surrounded by another star-forming region, LBN 867. Also known as SH 2-264, the Lambda Orionis molecular ring is sometimes called the Meissa ring. With an annual parallax shift of 8.64 mass, it is approximately 380 light years from Earth. As his punishment, Artemis banished the hunter to the sky where he can be seen as the famous constellation Orion. xmlns:xsl='http://www.w3.org/1999/XSL/Transform'">. Lambda Orionis is a hot, massive star that is surrounded by several other hot, massive stars, all of which are creating radiation that excites a ring of dust, creating the "Lambda Orionis molecular ring." In visible light, Orion's other shoulder is clearly marked by the variable star Bellatrix. In Latin, Bellatrix means "female warrior," which is perhaps why the name was chosen for a female witch character in the popular Harry Potter books. The Orion Molecular Cloud Complex also includes the famous Orion Nebula , De Mairan’s Nebula (Messier 43), the Horsehead Nebula, the Lambda Orionis molecular ring, the emission nebula Barnard’s Loop, and the reflection nebula Messier 78. The cluster might have formed in the central region of an elongated cloud, which is supported by the distribution of pre-main-sequence star candidates, which are concentrated in the cluster and nearby regions in an elongated shape. The H II region is about 150 light years or over 10 degrees across and illuminated by the ultraviolet light from … The distribution of molecular gas closely approximates that of the dust seen in IRAS emission.
