An artist's depiction shows how brief, bright bursts of radio waves travel through the fog between galaxies, known as the intergalactic medium. Each wavelength allows astronomers to “weigh” the ...

A team of astronomers in Australia searching for radio flashes from distant galaxies has found something a lot closer to home. The defunct communications satellite Relay 2, out of commission since ...

Astronomers have just spotted the brightest fast radio burst (FRB) ever seen—and for the first time, they know exactly where ...

Fast radio bursts (FRBs) are some of the universe’s most mysterious signals — immense flashes of radio waves that last only milliseconds but can outshine every other radio source in their galaxy.

"Fast radio bursts shine through the fog of the intergalactic medium, and by precisely measuring how the light slows down, we can weigh that fog, even when it's too faint to see." Half of the universe ...

A strange flash of light from near the beginning of the universe could help astronomers map difficult-to-see gas in between galaxies, like a flashbulb in a dark room. Fast radio bursts (FRBs) are ...

The Earth is constantly receiving space signals that contain vital information about extremely energetic phenomena. Among the most peculiar are brief pulses of extremely high-energy radio waves, known ...
