A Mysterious, Powerful Force Is Flinging Radio Waves at Us from Deep Space

Our universe is teeming with invisible light. Beyond the visible spectrum, space is a colorful mess of radio signals and microwaves fired off by flaring "suns," collapsing stars, crackling magnetic fields, roiling dust clouds and seething black holes.

Then, there's the light nobody understands — mysterious, ultrastrong sparks of energy zipping billions of light-years across the universe from unknown origins, for unknown reasons.

Puzzling pulses like these are sometimes called fast radio bursts (FRBs), because they may last just a few milliseconds. On the morning of July 25, one such burst of mysterious energy whizzed past a new array of radio telescopes nestled in the mountains of British Columbia, Canada, registering one of the rarest radio frequencies ever detected.

According to a statement released in The Astronomer's Telegram (a bulletin board of astronomical observations posted by accredited scientists), the mystery signal — named FRB 180725A after the year, month and day it was detected — transmitted in frequencies as low as 580 megahertz, nearly 200 MHz lower than any other FRBs ever detected.
