Read our privacy policy Mysterious blasts of intense energy, known as fast radio bursts, are coming from massive galaxies, scientists have said. Fast radio bursts were first found in 2017, when scientists spotted that very powerful, very short pulses of radio-frequency light occasionally lit up the sky. Our work helps to answer this question.” What’s more, it could offer clues about magnetars themselves, as well as fast radio bursts. A paper reporting the findings, ‘Preferential Occurrence of Fast Radio Bursts in Massive Star-Forming Galaxies’, is published in Nature.

Astronomers have pinpointed the origin of mysterious repeating radio bursts from space

Raw Story  

Slowly repeating bursts of intense radio waves from space have puzzled astronomers since they were discovered in 2022. We know some repeating radio signals come from a kind of neutron star called a radio pulsar, which spins rapidly, beaming out radio waves like a lighthouse. When the wind hits the white dwarf’s magnetic field, it would be accelerated, producing radio …

Astronomers pinpoint origin of mysterious repeating radio bursts from space

Deccan Chronicle  

Slowly repeating bursts of intense radio waves from space have puzzled astronomers since they were discovered in 2022.In new research, we have for the first time tracked one of these pulsating signals back to its source: a common kind of lightweight star called a red dwarf, likely in a binary orbit with a white dwarf, the core of another star …

Are aliens trying to contact Earth? Scientists reveal 'weird' origin of signal that traveled 8 billion years through space

Daily Mail  

Scientists have identified the 'weird' origin of a high-energy burst of radio waves that traveled eight billion years through space before reaching Earth. New NASA Hubble Space Telescope images have given the clearest images yet of the host galaxy of an exceptionally powerful fast radio burst, FRB 20220610A. Hubble's sensitivity and sharpness revealed that this distant galaxy is part of …

Scientists trace powerful radio signal to most distant galaxy yet

The Hindu  

Every day and night, hundreds of thousands of intense, brief flashes of radiation suddenly flicker on and then off all across the sky. These “fast radio bursts” are invisible to the naked eye, but to a radio telescope many almost outshine everything else in the sky for a few thousandths of a second. Fast radio bursts let us study the …

Scientists have traced down the source of several mysterious fast radio bursts

Daily Mail  

Thanks to NASA's Hubble Space Telescope, researchers have tracked down the origins of several mysterious fast radio bursts to five distant galaxies. The researchers were able to find the FRBs, thanks to the ultraviolet and near-infrared light spotted by the Hubble's Wide Field Camera 3. NASA's Hubble Space Telescope tracked down the origins of several fast radio bursts to galaxies …

Fast radio burst detected in the Milky Way is repeating, scientists confirm

Firstpost  

In April this year, a weaker burst was detected and astronomers tracked it to a unique kind of star called a magnetar some 30,000 light-years away from us. While at first, most FRBs were detected from outside our galaxy, objects within our Milky Way galaxy have also been detected to spit out radio bursts. But this theory was proven wrong …

New findings make fast radio bursts all the more intriguing

Live Mint  

Ever since they were discovered more than a decade ago, fast radio bursts, or FRBs—powerful, millisecond-duration radio waves that come from deep space—have kept astrophysicists guessing about their origins. Researchers working with the Canadian Hydrogen Intensity Mapping Experiment and the Survey for Transient Astronomical Radio Emission 2 —two radio telescope arrays—found conclusive evidence of radio bursts emerging from a magnetar …

Flash of luck: Astronomers find cosmic radio burst source

India Today  

A flash of luck helped astronomers solve a cosmic mystery: What causes powerful but fleeting radio bursts that zip and zigzag through the universe? This burst in less than a second contained about the same amount of energy that our sun produces in a month, and still that's far weaker than the radio bursts detected coming from outside our galaxy, …
