|Object||NGC 6726 (aka) Corona Austalis Nebula|
NGC 6761, part there of, is located in the southern constellation Corona Austalis. This image depicting the area/ reflection nebulosity is charged by the light given off from the young star R Coronae Australis (partly shrouded by the dust). Classified as a Herbig Ae/Be pre-main sequence star, having 10 times the mass of our own sun, Sol. The greater molecular complex continues down the R/H corner (not shown) and is believed to be one of the closest star forming regions to us situated around 500 l.y. away.
