Pulsars bumping into asteroids

Mystery radio bursts may be pulsars bumping into asteroids

Quote

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.

Fast radio bursts (FRBs) are a rare and mysterious phenomenon. Until recently, we had seen fewer than 20 of these milliseconds-long pulses of radio waves, and they have been attributed to everything from quasars to aliens.

Last year, astronomers at the Arecibo Observatory in Puerto Rico nearly doubled the number of observed FRBs when they saw 16 bright bursts from the direction of FRB 121102, where a single burst had been detected in 2012.
