L183 or L134N is a much-studied pre-stellar core in the constellation Serpens Cauda 360 light-years away. This massive accumulation of gas and dust was the interstellar object in which the phenomenon of coreshine was first investigated by astronomers and produced a new means of probing its previously opaque core.[http://www.aanda.org/index.php?option=com_article&access=standard&Itemid=129&url=/articles/aa/abs/2004/14/aa0087/aa0087.html L183 (L134N) Revisited - L.
