Discovery of second repeating fast radio burst raises new questions

An international team of astronomers has discovered a permanently active second fast radio burst, raising questions about the nature of the mysterious phenomenon.

Fast radio bursts (FRB) are intense, brief flashes of radio frequency emissions, lasting on the order of milliseconds. The phenomenon was discovered in 2007 by graduate student David Narkevic and his supervisor Duncan Lorimer. The source of these highly energetic events is a mystery, but clues to their nature are slowly being collected.
