      Explanation: Cosmic dust clouds cross a rich field of stars in this   
      telescopic vista near the northern boundary of Corona Australis, the   
      Southern Crown. Part of a sprawling molecular cloud complex this star   
      forming region is a mere 500 light-years away. That's about one third   
      the distance of the more famous stellar nursery known as the Orion   
      Nebula. The 2 degree wide frame would span 15 light-years at the   
      clouds' estimated distance. Mixed with bright nebulosities the dust   
      clouds effectively block light from more distant background stars in   
      the Milky Way and obscure from view embedded stars still in the process   
      of formation. Large dark nebula Bernes 157 is on the left. To its right   
      are a group of pretty reflection nebulae cataloged as NGC 6726, 6727,   
      6729, and IC 4812. Their characteristic blue color is produced as light   
      from hot stars is reflected by the cosmic dust. The more compact NGC   
      6729 surrounds young variable star R Coronae Australis. Just below it,   
      filamentary arcs and loops are identified as Herbig Haro objects   
      associated with energetic newborn stars. In fact, at the heart of this   
      area lies the Coronet Cluster, one of the nearest and most active star   
      forming regions.
