The constellation Corona Australis contains one of the closest star-forming regions to the Solar System—a dusty dark nebula known as the Corona Australis Molecular Cloud, lying about 430 light years away. Within it are stars at the earliest stages of their lifespan. It contains many embedded reflection nebulae,including NGC 6729, NGC 6726–7, and IC 4812. A star-forming region of around 7000 solar masses, it contains Herbig–Haro objects (protostars) and some very young stars. This nebula is one of the closest star-forming regions to the Solar System. The related NGC 6726 and 6727, along with unrelated NGC 6729, were first recorded by Johann Friedrich Julius Schmidt in 1865 (Wikipedia). The globular cluster NGC 6723 is unrelated to the nebula, and is much farther, 28000 light years away. Several galaxies are visible in the background.
