Description of

|
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. |
