This composite image reveals the hidden power sources of this volatile star forming region. Blue represents starlight as seen by the UK Infrared Telescope (UKIRT), green is Herschel's view of the heated gas by ultraviolet radiation from protostars, and red is cooler gas seen by the Caltech Submillimeter Observatory. X marks the outburst, an area astronomers will keep an eye on. (Credit: J. Green, Univ. of Texas/ESA/UKIRT/CSO)
