Abstract

The MidCourse Space eXperiment (MSX) surveyed theGalactic planewithin 5° latitude in four mid-infrared spectral bands. A setof full resolution (20'') 1.5°×1.5° images on 6'' pixelcenters has been created in each spectral band by co-adding all thesurvey data. A lower (1.2') resolution atlas of 10°×10°images provide large-scale panoramas of the plane. A new class ofobjects has been identified in the images, infrared dark clouds, whichare silhouetted against the mid-infrared background emission from theinterstellar medium in the Galactic plane. The IRAS ISSA platesindicate that these clouds are dark out to 100 μm. Submillimeteremission traces the form of the dark cloud and reveals coresindicative of class 0 protostars.
