powerful radio signal from distant galaxy

Since 2007, just 85 cosmic radio wave bursts have been detected, according to the Independent. For the first time, the origin of a single radio pulse has been pinpointed to a distant galaxy several billion light years away, a new study said. “These bursts are altered by the matter they encounter in space,” said Jean-Pierre Macquart, study co-author from Curtin University in Australia. The team analyzed 28 bursts between September 2018 and October 2019 recorded by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/FRB), a radio telescope in British Columbia, Canada. Fast radio bursts have raised far more questions about the universe than they can answer. Now, Vice reports, a new study by Cornell University researchers has identified an FRB source about half a billion light years from Earth that pulses, ominously, on a regular 16-day cycle. Astronomers suggest the signal may have originated as a result of massive, shifting gravitational forces causing a starquake or magnetar flare, a disturbance in the magnetic field surrounding it. A team of Cornell University researchers have spotted a fast radio signal source … As for what the bursts are, ideas range from a rotating neutron star to, yes, a high-powered signal from an advanced civilization. "We cannot rule out completely the extraterrestrial hypothesis for the fast radio bursts in general," Vishal Gajjar, a postdoctoral fellow at the University of California-Berkeley, said last year.

Some have even speculated they could be signs of extraterrestrial life. For the first time, the origin of a single radio pulse has been pinpointed to a distant galaxy several billion light years away, a new study said. We’ve only started to understand these powerful signals and have yet to figure out their cause. "This is the big breakthrough that the field has been waiting for since astronomers discovered fast radio bursts in 2007," said study lead author Keith Bannister of Australia's Commonwealth Scientific and Industrial Research Organisation. The signal, a millisecond-wave bursts of radio waves, was traced back to a Milky Way magnetar, a type of neutron star with an extremely strong magnetic field.

They’re extremely unpredictable, despite some of them releasing more energy than 500 million suns.
