A planet is first pulled away from its parent star by the gravity of the dense concentration of stars in a globular cluster. When such a planet passes too close to a white dwarf,it can be torn apart by the intense tidal force of the white dwarf.The planetary debris is then heated & glows in X-rays. via /r/spaceporn http://bit.ly/2X3QMFs
