The constellation Corona Australis is a fascinating region of the night sky, containing stellar objects that are at the extremes of age and distance. These include one of the closest star forming regions to the Solar System – a dusty dark nebula known as the Corona Australis Molecular Cloud. Lying at a distance of 430 light years, the Cloud is populated by protostars at the very beginning of their stellar life cycle, as well as several blue reflection nebulae. Nearby (and towards the bottom left of the image) is the globular cluster NGC6723, with an estimated age of 13.05 billion years. Also within the field of view are numerous distant background galaxies (identified in the attached annotated image with their “PGC” catalogue numbers).
