摘要：
Deep photometry around the Galactic globular clusters NGC 1851 and NGC 1904 obtained with the Wide Field Imager in the 2.2 m ESO telescope reveals a distinct main-sequence of a metal-poor stellar population, consistent with the presence of a very low surface brightness stellar system. The unveiled population might belong to an unknown tidal stream in the Milky Way but other possibilities are here discussed.
