Starbursts in Colliding Galaxies

Contrasting regions of intensive star formation appear in infrared light from a pair of galaxies in collision, observed by the European Space Agency's new Infrared Space Observatory, ISO. The Camera in ISO (also called ISOCAM) obtained this image at a wavelength of 15 microns, where the Earth's atmosphere makes cosmic observations very difficult - hence the need for Europe's space telescope dedicated to infrared astronomy.
