Glossary term: 암흑성운
Description: 암흑성운은 우주 공간에 있는 가스와 먼지로 이루어진 차가운 구름입니다. 이 성운은 그 뒤쪽에 있는 별빛이나 밝은 성운의 빛을 거의 모두 가려 버리기 때문에 어둡게 보입니다. 성운 속의 먼지는 전체 물질의 약 1%밖에 되지 않지만, 빛을 가리는 역할은 대부분 이 먼지가 합니다. 암흑성운은 가시광선이나 자외선의 빛은 막지만, 적외선은 통과시킬 수 있습니다. 그래서 적외선 망원경으로 보면 암흑성운 내부의 구조나 그 뒤쪽의 천체들을 볼 수 있습니다. 가장 유명한 암흑성운의 예는 오리온자리의 말머리 성운입니다. 이름 그대로 말의 머리처럼 생긴 어두운 구름 모양이 인상적입니다.

Dust Clouds and Nebulae near R Coronae Australis
Caption: 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.
