Astronomers have fresh insight on a mysterious source of recurring radio pulses from space.
Researchers from around the world are scratching their heads over a newly discovered radio burst detected on Earth, but with a completely unknown origin.
Fast radio bursts, or FRBs, are mysterious flashes of radio waves originating outside our Milky Way galaxy. A team of scientists, jointly led by Caltech postdoctoral scholar Vikram Ravi and Curtin University research fellow Ryan Shannon, has now observed the most luminous FRB to date, called FRB 150807.
It’s a case of pulsar ping-pong. Repeating radio bursts from space may be the result of pulsars colliding with asteroids in faraway stellar systems.
