Scientific paper

The information gained from all-sky surveys at IR wavelengths is summarized, with emphasis placed on observations of the Galaxy. The characteristics and behavior of dust grains are described, particularly the absorption and radiative features and their significance for star formation. IR observations have revealed the locations of new stars enveloped in hot dust shells and of protoplanetary nebulae filled with exotic molecules. The existence of interstellar masers emitting power equivalent to the sun's output was detected in the IR. The IRAS has yielded far-IR data on 250,000 new sources which will be further examined with ground- and space-based instruments. Finally, the capabilities of current European telescopes for all-sky IR surveys are outlined and future space-based IR telescopes are described.
