An international team of astronomers has discovered a second persistently active fast radio burst (FRB), posing questions about the nature of these mysterious phenomena. FRBs are intense, brief flashes of radiofrequency 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 as to their nature are being gradually collected.
