A team of astronomers has
discovered a second persistently active fast radio burst, questioning about the nature of the mysterious phenomena
Fast radio bursts (FRBs)
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 as to their nature are being gradually collected.
The new source, Fast radio
burst 20190520B, was detected with the Five hundred-meter Aperture Spherical radio Telescope (FAST) in Guizhou, China
The discovery raises new
questions, if the sources of the FRBs evolve, or alternatively whether different kinds of sources are capable of emitting FRBs
