  • , The 305-metre Arecibo telescope, in Puerto Rico, and its suspended support
platform of radio receivers is shown amid a starry night.  A flash from the Fast Radio Burst source FRB 121102 is seen: originating beyond the Milky Way, from deep in extragalactic space.  This radio burst is highly polarized, and the polarized signal gets twisted as a function of radio frequency because there is an extreme region of magnetized plasma between us and the source of the bursts.
