Color-composite image of the massive star forming complex G333 , observed as part of a large project with the 22-m Mopra radio telescope near Coonabarabran, NSW. The colors depict the following temperature and density sensitive molecular line tracers: HCN tracing warm gas (around 20 to 40 K) , HCO + tracing warm gas with outflow/infall , and N 2 H + tracing really cold gas (less than 20 K) .
