This very detailed enhanced-colour image from ESO’s Very Large Telescope shows the dramatic effects of very young stars on the dust and gas from which they were born in the star-forming region NGC 6729. The baby stars are invisible in this picture, being hidden behind dust clouds at the upper left of the picture, but material they are ejecting is crashing into the surroundings at speeds of that can be as high as one million kilometres per hour. This picture was taken by the FORS1 instrument and records the scene in the light of glowing hydrogen and sulphur.

This picture shows the probable directions of the ejected material and indicates the positions of the Herbig-Haro objects (marked as HH) where ejected material is creating glowing shockwaves.

This chart shows the location of a rich star-forming region within the constellation of Corona Australis. This map shows most of the stars visible to the unaided eye under good conditions and the star-forming region NGC 6729, and its surroundings, are marked as a red circle. Although most of this stellar nursery is hidden by dust, the brighter reflection nebulae are faintly visible in moderate-sized telescopes.
