A Reddish Portrait from Barnard’s Loop with Boogeyman Dark Nebula and M78
Alqueva´s Dark Sky Reserve | By Year: 2024 | Deep Sky Wide Field
The image features an HaRGB wide deep sky portrait immersed in the reddish hues from hydrogen alpha emission, where part of the larger semi-circle (Sh2-276) that stands around the belt and sword of Orion, also known as Barnard’s Loop, is shiningly visible like a dense intricate wave across the scene. Located at a distance of 1600 light-years away, the entire loop spans at about 300 light-years across in space and belongs to an even bigger Molecular Cloud of dust and gas, made up of molecular hydrogen and helium. These clouds are the birth place for stars, forming out of the material in the cloud. Above the “reddish loop” and near the top edge of the image, is possible to enjoy LDN 1622, a large dark nebula also known as Boogeyman, located at 500 light-years away. Below the center wave are visible two reflection nebulas M78 and NGC 2071. M78 lies at approximately the same distance as Barnard’s Loop but it only spans 5 light-years in space. The image was captured from Dark Sky® Alqueva Observatory, Cumeada, in Portugal.
PT: A imagem revela um campo amplo e profundo de HaRGB imerso nos tons avermelhados da emissão hidrogénio-alfa, onde parte do semicírculo maior (Sh2-276) que fica ao redor do cinturão e da espada de Orion, também conhecido como Loop de Barnard, é visível brilhando como uma onda densa e intrincada que atravessa toda a imagem. Localizado a uma distância de 1.600 anos-luz de distância, todo o Loop se estende por cerca de 300 anos-luz de diâmetro no espaço e pertence a uma Nuvem Molecular ainda maior de poeira e gás, composta de hidrogénio molecular e hélio. Essas nuvens são o local de nascimento das estrelas, formadas a partir do material da nuvem. Acima do “Loop avermelhado” e próximo ao extremo superior da imagem, é possível apreciar LDN 1622, uma grande nebulosa escura também conhecida como Boogeyman, localizada a 500 anos-luz de distância. Abaixo da onda central são visíveis duas nebulosas azuladas de reflexão M78 e NGC 2071. M78 fica aproximadamente à mesma distância do Loop de Barnard, mas se estende por apenas 5 anos-luz no espaço. A imagem foi captada a partir do Observatório Oficial do Dark Sky® Alqueva, na Cumeada, Portugal.
