A binary star system in the Milky Way Galaxy consisting of a compact object, possibly a black hole, that accretes matter in the form of a disk from an early-type companion star. The most remarkable feature of the system is the presence of bipolar narrow outflows of matter, jets, with a velocity of 26% the speed of light, whose ejection axes change with time.
