The Trifid Nebula in the constellation Sagittarius changes its appearance dramatically when seen by infrared light by ESA's Infrared Space Observatory ISO. In the picture obtained by ISO's camera ISOCAM, the regions of strongest emissions correspond with dark bands seen by visible light by a Spanish ground-based telescope. The infrared image looks like a negative of the visible nebula.
