A spinning neutron star periodically swings its radio (green) and gamma-ray (magenta) beams past Earth in this artist’s concept of a black widow pulsar. The pulsar heats the facing side of its stellar partner to temperatures twice as hot as the sun’s surface and slowly evaporates it. | Photo Credit: Reuters How fast can a…
