Description This image, based on data obtained with the Wide Field Imager (WFI) camera attached to the 2.2-m Max-Planck/ESO telescope through four different filters (B, V, R, and H-alpha), shows the amazing intricacies of the vast stellar nursery Gum 29. At its centre lies the cluster of young stars Westerlund 2. One object at the bottom of the cluster is in fact a system of two of most massive stars known to astronomers.
