We present observations of L1014, a dense core in the Cygnus regionpreviously thought to be starless, but data from the Spitzer Space Telescopeshows the presence of an embedded source. We propose a model for this sourcethat includes a cold core, heated by the interstellar radiation field, and alow-luminosity internal source. The low luminosity of the internal sourcesuggests a substellar object. If L1014 is representative, other "starless"cores may turn out to harbor central sources.Comment: 7 pages, To appear in the ApJS Spitzer Special Editio
