The discovery of the second fast radio burst raises new questions

An international team of astronomers has discovered a second persistently active fast radio burst, questioning the nature of the mysterious phenomenon.

Fast radio burst (FRB) is an intense, short flash of radio frequency radiation that lasts on the order of milliseconds. This phenomenon was discovered in 2007 by graduate student David Narkevic and his supervisor Duncan Lorimer. The source of these very energetic events is a mystery, but clues about their nature are gradually being gathered.
