Astronomers using the NASA/ESA Hubble Space Telescope, along with other telescopes on the ground and in space, have discovered a new type of exotic binary star: in the system AR Scorpii a rapidly spinning white dwarf star is powering electrons up to almost the speed of light. These high energy particles release blasts of radiation that lash the companion red dwarf star, and cause the entire system to pulse dramatically every 1.97 minutes with radiation ranging from the ultraviolet to radio.

The release, images and videos are available on:

A galaxy fit to burst  A lonely birthplace  A stubborn dwarf galaxy  Bursting at the seams  The stars of the Large Magellanic Cloud
