description NGC 6729 Overview
NGC 6729 is a variable emission and reflection nebula located within the Corona Australis molecular cloud complex. Discovered by astronomer Julius Schmidt in 1861, the cloud's illumination is driven by the variable young T Tauri star R Coronae Australis. As the brightness of R CrA fluctuates, the associated nebula visually changes in luminosity, a phenomenon studied by astronomers observing early stellar evolution.
help NGC 6729 FAQ
What makes NGC 6729 change in brightness and shape?
NGC 6729 reflects and emits light associated with the young variable star R Coronae Australis, or R CrA. Dust moving close to the star changes which parts of the surrounding nebula are illuminated, producing visible variations.
Where is NGC 6729 in the night sky?
The nebula lies in the southern constellation Corona Australis, near the stars R CrA and T CrA. It belongs to a larger star-forming complex that also contains the reflection nebulae NGC 6726 and NGC 6727.
Who discovered NGC 6729?
German astronomer Johann Friedrich Julius Schmidt discovered it in 1861. Its variable illumination later made it a notable example of a variable nebula.
Can NGC 6729 be seen with a small telescope?
It is a challenging visual target because it is faint and embedded in a dusty region. Dark southern skies, a moderate or large telescope, or long-exposure astrophotography provide a much better view than a small instrument under city lights.
