Blue Horsehead Nebula and Rho Ophiuchi Cloud Complex in a Colorful Deepsky Scene
Alqueva´s Dark Sky Reserve | By Year: 2020 | Deep Sky Wide Field
The image features a wide view of Blue Horsehead Nebula IC 4592 and Rho Ophiuchi Cloud Complex, one of the most colourful nebulas in space and the closest star-forming regions to the Solar System, at an estimated distance of 460 light years. These interstellar clouds of gas and dust contain both red emission nebulas and blue reflection nebulas. The dark brown regions are caused by dust grains, born in young stellar atmospheres, which effectively block light emitted behind them. The lower area of the image features many dark absorption nebulas. The dark cloud known as “Dark River”, it can be identified as the brown dust lane connected to Antares, and spans about 100 light years in direction of the central band of our Milky Way Galaxy. The distant globular cluster M4 is just seen above the red supergiant star Antares, one of the brighter stars in the night sky, though it lies far behind the colourful cloud complex, at a distance of some 7,000 light-years.
PT: A imagem apresenta uma visão ampla da nebulosa Blue Horsehead IC 4592 e do complexo de nuvens Rho Ophiuchi, um dos complexos nebulosos mais coloridos do espaço e uma das regiões de formações de estrelas mais próximas ao sistema solar, localizado a uma distância estimada de 460 anos-luz, estas nuvens inter-estelares de gás e poeiras contêm nebulosas de emissão (vermelhas) e nebulosas de reflexão (azul). As regiões a castanho escuro são causadas por grãos de poeira, nascidos em atmosferas estelares jovens, que efetivamente bloqueiam a luz emitida por detrás delas. A região inferior da imagem apresenta ainda muitas nebulosas de absorção escuras. A nebulosa escura conhecida como “Dark River”, pode ser identificada como a banda de poeira castanha que está conectada à região de Antares e que se estende por 100 anos-luz de distância em direcção à banda central de nossa Galáxia, a Via Láctea. O aglomerado globular M4 pode ser visto nesta imagem, à esquerda da estrela super gigante vermelha Antares, uma das estrelas mais brilhantes do céu noturno, este aglomerado está no entanto bem atrás do complexo colorido, a uma distância de cerca de 7.000 anos-luz.
