L1014 is a dark nebula in Cygnus constellation. It may be among the most centrally condensed small dark cloud known, perhaps indicative of the earliest stages of star formation processes. This cloud harbours at its core a very young low-mass star, named L1014 IRS; some astronomers have suggested that this star may be a brown dwarf at the earliest stage of its lifetime.[3]
