The spectacular reflection nebula known
as the Corona Australis nebula dominates this wonderful cosmic
scene. However on closer inspection several subtle but equally
intriguing structures are evident. The field is rich not only
in bright and dark nebulae, but also fascinating variable stars,
variable nebulae, and stellar outflows. R CrA is an irregular
variable star buried within the small yellow cloud which varies
in brightness along with its surrounding nebula. R CrA is flanked
by two equidistant red patches formed by invisible protostars
that which are still accreting mass and have yet to enter the
main sequence. The red patches represent herbig-haro objects made
visible by the energetic outflows of yet invisible young stars.
The main nebula complex is flanked by the dark nebula Barnes 157
in the lower left and the globular cluster NGC 6723 in the upper
right.
