Caption: The most common type of multiple-star systems are those with two stars, which astronomers call “binaries.” Some of these pairs contain a star similar to the Sun in orbit with a much denser object such as a neutron star or black hole. These are known as “X-ray binaries” because the dense object often generates X-rays. In this case, material from the companion star is being pulled toward a black hole, which powers a jet outward into space.
