Fast radio bursts, or FRBs, are cosmic radio bursts that last only milliseconds. Since then, 36 have been found — 19 last year alone by researchers using an Australian radio telescope. In 2015, McGill University PhD student Paul Scholz found that a previously detected FRB actually repeated. This visible-light image shows the host galaxy of the fast radio burst FRB 121102. "We don't see these kinds of structures from other fast radio bursts that are in a single burst," said Tendulkar.
