图片说明
The image shows a dark and dusty cloud and some bright reflection nebulae near the binary star R Coronae Australis. The dark cloud spans several light-years and is located in the constellation Corona Australis near the constellation Sagittarius, in the direction of the Milky Way's center. The cloud appears to swallow the light of distant stars behind it as the dust particles in it scatter light passing through in all directions. This gives it the appearance of a void in the sky. This dark nebula is part of the broader Corona Australis Molecular Clouds. R Coronae Australis forms part of the Coronet Cluster, a collection of young stars which formed at some point in the last two million years.
Around R Coronae Australis in the center of the image is the small reflection nebula NGC 6729 with two blueish reflection nebulae NGC 6726 and NGC 6727 lying to the upper right of it. In these nebulae the dust scatters light from bright stars near the nebula towards an observer on Earth, making it glow in this image.

图片说明 Das Bild zeigt eine dunkle, staubige Wolke und einige helle Reflexionsnebel in der Nähe des Doppelsterns R Coronae Australis. Die Dunkelwolke erstreckt sich über mehrere Lichtjahre und liegt im Sternbild Corona Australis in der Nähe des Sternbilds Schütze, in Richtung des Zentrums der Milchstraße. Die Wolke scheint das Licht der fernen Sterne hinter ihr zu verschlucken, da die Staubteilchen in ihr das eingestrahlte Licht in alle Richtungen streuen. Dadurch wirkt sie wie eine Leere am Himmel. Dieser Dunkelnebel ist Teil der ausgedehnteren Corona Australis-Molekülwolken. R Coronae Australis ist Teil des Coronet-Haufens, einer Ansammlung von jungen Sternen, die irgendwann in den letzten zwei Millionen Jahren entstanden sind.
Um R Coronae Australis in der Mitte des Bildes befindet sich der kleine Reflexionsnebel NGC 6729, rechts oben liegen die beiden bläulichen Reflexionsnebel NGC 6726 und NGC 6727. In diesen Nebeln streut der Staub das Licht von hellen Sternen in der Nähe des Nebels in Richtung eines Beobachters auf der Erde, so dass er in diesem Bild leuchtet.

图片说明 L'immagine mostra una nube scura e polverosa e alcune luminose nebulose a riflessione vicino alla stella binaria R Coronae Australis. La nube scura si estende per diversi anni luce e si trova nella costellazione di Corona Australis, vicino alla costellazione del Sagittario, in direzione del centro della Via Lattea. La nube sembra inghiottire la luce delle stelle lontane dietro di sé, poiché le particelle di polvere in essa contenute disperdono la luce che passa in tutte le direzioni. Ciò le conferisce l'aspetto di un vuoto nel cielo. Questa nebulosa scura fa parte della più ampia nube molecolare Corona Australis. R Coronae Australis fa parte dell'Ammasso Coronet, un insieme di giovani stelle che si sono formate negli ultimi due milioni di anni.
Intorno a R Coronae Australis, al centro dell'immagine, si trova la piccola nebulosa a riflessione NGC 6729 con due nebulose a riflessione bluastre NGC 6726 e NGC 6727 situate in alto a destra. In queste nebulose la polvere diffonde la luce delle stelle luminose vicine alla nebulosa verso un osservatore sulla Terra, facendola brillare in questa immagine.

图片说明 A imagem mostra uma nuvem escura e empoeirada e algumas nebulosas de reflexão brilhantes perto da estrela binária R Coronae Australis. A nuvem escura se estende por vários anos-luz e está localizada na constelação Corona Australis, perto da constelação de Sagitário, na direção do centro da Via Láctea. A nuvem parece engolir a luz de estrelas distantes atrás dela, pois as partículas de poeira nela contidas dispersam a luz que passa em todas as direções. Isso lhe dá a aparência de um vazio no céu. Esta nebulosa escura faz parte das Nuvens Moleculares de Corona Australis, uma região mais ampla. R Coronae Australis faz parte do Aglomerado Coronet, um conjunto de estrelas jovens que se formou em algum momento nos últimos dois milhões de anos.
Ao redor de R Coronae Australis, no centro da imagem, encontra-se a pequena nebulosa de reflexão NGC 6729, com duas nebulosas de reflexão azuladas NGC 6726 e NGC 6727 situadas no canto superior direito. Nessas nebulosas, a poeira dispersa a luz de estrelas brilhantes próximas, direcionando-a para um observador na Terra, fazendo-a brilhar nesta imagem.
