Nobody noticed when an Australian radio telescope captured a fleeting explosion coming from far beyond the Milky Way in 2001. Records of the powerful flare sat unseen for more than half a decade until ...

For 8 billion years, a burst of radio waves packing more energy than what the sun produces in three decades made its way across the farthest reaches of the cosmos before its light finally reached ...

Mysterious fast radio bursts, or millisecond-long bright flashes of radio waves from space, have intrigued astronomers since the first detection of the phenomenon in 2007. The enigmatic signals, known ...

The use of "radio colors" led to the breakthrough. In optical light, colors are how the eye distinguishes each wavelength. Our rainbow goes from shorter-wavelength blue optical light, to ...

Most fast radio bursts come from quiet galaxies like ours, suggests a recent study which traced 28 of them to their sources. Fast radio bursts are exactly what they claim to be: short, intense bursts ...

Fast radio bursts, or FRBs – powerful, millisecond-duration radio waves coming from deep space outside the Milky Way Galaxy – have been among the most mysterious astronomical phenomena ever observed.

Every now and then, astronomers will detect an odd kind of radio signal. So powerful it can outshine a galaxy, but lasting only milliseconds. They are known as fast radio bursts (FRBs). When they were ...

One of the rare and brief bursts of cosmic radio waves that have puzzled astronomers since they were first detected nearly 10 years ago has finally been tied to a source: an older dwarf galaxy more ...

A newly discovered fast radio burst has some unique properties that are simultaneously giving astronomers important clues into what may cause these mysterious astronomical phenomena while also calling ...
