    Mysterious Deep-Space Flashes: 19 More 'Fast Radio Bursts' Found

    Mysterious Deep-Space Flashes: 19 More 'Fast Radio Bursts' Found

    Multi second long bursts that produce as much energy as our sun in a century. I'd say that is a lot of energy.

    A huge haul of newfound fast radio bursts (FRBs) may help astronomers finally start to get a handle on these mysterious and powerful blasts from deep space.

    A new study reports the detection of 19 previously undiscovered FRBs, including the closest one to Earth and the brightest one ever seen. The results boost the total tally significantly; just three dozen or so FRBs had been known previously, with the first detection coming in 2007.


    FRBs are brief (millisecond-long) but intense emissions of radio light, which can pack as much energy as our own sun produces over the course of nearly a century. Their source is the topic of much discussion and debate. For example, some researchers have suggested that FRBs could be generated by advanced alien civilizations, though most astronomers favor natural explanations, such as fast-spinning neutron stars.

    The new study is led by Ryan Shannon, of the Swinburne University of Technologyin Australia. Since the beginning of 2017, he and his team have been searching the skies for FRBs using the Australian Square Kilometer Array Pathfinder (ASKAP), a network of 36 radio dishes in Western Australia.


    The systematic hunt has already turned up 20 FRBs, the researchers report in the new paper, which was published online today (Oct. 10) in the journal Nature. (One of the bursts they spotted was reported previously in a different paper, so the count of newfound FRBs technically stands at 19.)


    The team's success rate can be traced to two factors, said study co-author Keith Bannister of the Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia's national science agency, which designed and engineered ASKAP.
