GRO J1655-40 is moving the black hole due to a supernova. French and Argentine astronomers have detected with the Hubble telescope and have observed a star that has not been destroyed by the explosion, which are close to each other, so the black hole is swallowing the gas of that star.

The stellar duo is at 6,000-9,000 light-years from Earth, in the direction of the constellation of Scorpio, and moves at 400,000 kilometers per hour. Black holes have never been detected in the plane of the galaxy that move at high speed.

The particles that pour the black hole give the system the appearance of a mobile torch. Astronomers have proposed the word microquasar to designate these systems.
