When Cornell built the Arecibo radio telescope in Puerto Rico more than 60 years ago, it was the world's largest. Now, ...

Fast radio bursts, strong pulses of energy detected in radio-wave frequencies, may be a common phenomenon in the cosmos, but their enigmatic origins are something astronomers are only beginning to ...

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 ...

If not in visible stars and galaxies, the most likely hiding place for the matter is in the dark space between galaxies.

For almost two decades, astronomers have detected extremely powerful, millisecond-long flashes of radio waves known as fast radio bursts (FRBs) from beyond our galaxy—and had no clue where they came ...

Astronomers located hyperactive fast radio bursts to a faint dwarf galaxy orbiting a larger companion 2 billion light-years ...

Using the Large Phased Array (LPA) and the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers from Russia and China have observed a nearby pulsar designated PSR J1951+2837. The ...

A staccato blast of electromagnetic energy has been tracked to an old, dead galaxy for the first time. The discovery supports the idea that there are more ways to produce such flares, called fast ...

The first trial of an Australian-developed technology has detected mysterious objects by sifting through signals from space like sand on a beach. Astronomers and engineers at CSIRO, Australia's ...

A powerful blast of energy detected in March marks the brightest fast radio burst — a mysterious type of outburst from space — observed to date. FRBs, first observed in 2007, are millisecond-long ...

In the hills of China’s Guizhou province, a natural rock bowl cradles the world’s largest single-dish radio telescope. This instrument, called FAST—the Five-Hundred-Meter Aperture Spherical Radio ...

With their extremely strong magnetic fields, magnetars have long been considered the prime culprit capable of producing the powerful bursts of energy known as fast radio bursts. The recent burst, ...
