IRAS observations of extended zodiacal structuresIn 1983, the Infrared Astronomical Satellite discovered two pairs of dust bands, straddling the ecliptic plane and located in the asteroid belt. New analysis of the IRAS data has resulted in the detection of as many as eight additional bands, spread over more than 40 deg of ecliptic latitude. Dust band morphology is found to vary between different band pairs, having a typical apparent width of a few degrees. This limits the total number of bands which can be distinguished to near the number observed. The Tempel 2 and Encke dust trails are observed to extend over much more of their orbits than had been previously reported, and a new type of dust trail is found which has a relatively large angular width and no imbedded cometary source.
