About this image

The pillars in the star-forming region surrounding Westerlund 2, composed of dense gas, are a few light-years tall and point to the central cluster. They are thought to be incubators for new stars. Besides sculpting the gaseous terrain, intense radiation from the most brilliant of the cluster stars is creating a successive generation of baby stars. The bluish haze is an indicator of oxygen gas in the nebula.
