Webdark clouds that contained stars associated with so-called cometary reflect-ing nebulae. Later the list of targets for the survey was supplemented by dark clouds with embedded bright infrared sources. The first results of this survey, relating to the star-formation regions Mon RI and LDN 1652, were previously published in Refs. 1 and 2. WebThe Oort Cloud is a reserve of cometary nuclei that contain ices dating back to the origin of the solar system. No one knows for sure how many objects exist in the Oort Cloud, but most estimates put it at around 2 trillion. The planetoid Sedna, discovered in 2003, is thought to be a member of the inner Oort Cloud.
