This animation provides a 3D perspective on Hubble‘s 25th anniversary image of the nebula Gum 29 and the star cluster Westerlund 2 at its core. It begins fly past foreground stars and approaches the rim of the nebula. After passing through the wispy darker clouds on the near side, the simulation shows the bright gas illuminated by the intense radiation of the new stars forming in the Westerlund 2 cluster. The pillars of dark, dense gas are being sculpted by light and strong stellar winds from thousands of stars. This visualization is intended to be a scientifically reasonable interpretation, but distances within the model have been significantly compressed.
