Jets and ejecta from neutron star merger (IMAGE) University of California - Berkeley Caption In this artist's representation, the merger of two neutron stars to form a black hole (hidden within bright bulge at center of image) generates opposing, high-energy jets of material (blue) that heat up material around the stars, making it emit X-rays (reddish clouds). X-rays also could be produced during violent collisions as material falls into the black hole (yellowish disk around central bulge).
