Mystery radio waves from far outside galaxy.

VOA News: Astronomers in Canada have detected a mysterious volley of radio waves from far outside our galaxy.

Fast radio bursts (FRBs) flash only for a micro-instant, but can emit as much energy as the sun does in 10,000 years.

Exactly what causes these high-energy surges of long waves at the far end of the electromagnetic spectrum remains the subject of intense debate.

“FRBs, it seems, are likely generated in dense, turbulent regions of host galaxies,” [said] Shriharsh Tendulkar, a corresponding author for both studies and an astronomer at McGill University.

Maybe in space, your screams are heard.
