The Globular Cluster NGC 6723 in the constellation Southern Crown

Description of object:

The Corona Australis complex, in the constellation southern crown, is one of the closest star birth regions in our cosmic environment. The distance is only around 400 light years. The associated dark nebula contains the raw materials for star births and is one of the densest areas in the sky. Parts of the cloud look like they are completely devoid of stars because the light of the background stars is extremely diminished in the visible part of the spectral region. The heaviest of the new born stars create several reflection nebulas. Furthermore, it is possible to see 3 Herbig-Haro objects: HH-99, HH-100 and HH-101. These objects are formed by material jets of newly born stars.

The dark cloud is very well defined on its northwestern border, and it is possible to see objects which are much further away, such as the globular cluster NGC 6723 with a distance of approximately 28000 light years.
