We present archival high angular resolution (∼2'') ¹²CO(3-2) line and continuum submillimeter observations of the young stellar object HL Tau made with the Submillimeter Array. The ¹²CO(3-2) line observations reveal the presence of a compact and wide opening angle bipolar outflow with a northeast to southwest orientation (P.A. = 50°) that is associated with the optical and infrared jet emanating from HL Tau with a similar orientation. On the other hand, the 850 µm continuum emission observations exhibit a strong and compact source in the position of HL Tau that has a spatial size of ∼200x70 AU with a P.A. = 145° and a dust mass of around 0.1 M_☉. These physical parameters are in agreement with values obtained recently from millimeter observations. This submillimeter source is therefore related to the disk surrounding HL Tau.
