Glowing Stellar Nurseries (IMAGE) ESO Caption Color composite image of RCW120. It reveals how an expanding bubble of ionized gas about ten light-years across is causing the surrounding material to collapse into dense clumps where new stars are then formed. The submillimeter-wavelength data were taken with the LABOCA camera on the 12-m Atacama Pathfinder Experiment (APEX) telescope. Here, the submillimeter emission is shown as the blue clouds surrounding the reddish glow of the ionized gas (shown with data from the SuperCosmos H-alpha survey). The image also contains data from the Second Generation Digitized Sky Survey (I-band shown in blue, R-band shown in red).
