The recently detected FRB, known as FRB 180916.J0158+65, sends out bursts that last for four days before stopping for 12 days and then repeating. And no one knows why. All rights reserved. Jarrett (IPAC/Caltech); B. Saxton, NRAO/AUI/NSF)


All market data delayed 20 minutes. A mysterious object in a galaxy 500 million light-years away is confusing scientists with its signals. Now, for the first time, astronomers have found a fast radio burst (FRB) that repeats on a regular cycle. $600 in jobless benefits end: "An impossible situation"James Murdoch resigns from News Corp board over editorial differencesFlorida teen charged as "mastermind" behind massive Twitter hackAppeals court overturns death penalty for Boston Marathon bomberHurricane Isaias slams the Bahamas and takes aim at FloridaThis student is on the way to college after stranger's donationBattleground Tracker: Latest polls, state of the race and more5 things to know about CBS News' 2020 Battleground TrackerBattleground Tracker: COVID reshapes presidential race in Sun BeltDNC hopes to reach more voters with new voter file model The first 28 …

"The discovery of a 16.35-day periodicity in a repeating FRB source is an important clue to the nature of this object. The first 28 cycles were observed between September 2018 and October 2019 using the CHIME radio telescope in British Columbia. or redistributed. Then it falls silent for 12 days. "We conclude that this is the first detected periodicity of any kind in an FRB source," the study's authors said. But discovering more repeating FRBs may be the only way to know for sure. ©2020 FOX News Network, LLC. It appears to be transmitting signals that reach Earth in a repeating, 16-day pattern, but researchers have no idea why.

This material may not be published, broadcast, rewritten, But the clue — a repeating 16-day pattern in one of the bursts, undermines one of the most popular theories for where the bursts are coming from. "Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven't identified a possible natural source with any confidence," Avi Loeb, a Harvard-Smithsonian Center for Astrophysics theorist, said in There is one source most scientists have generally ruled out: aliens. But FRBs will remain a mystery. Then it falls silent for 12 days. The series of "fast radio bursts" – short-lived pulses of radio waves that come from across the universe – were detected about once an hour for four days and then stopped, only to … ©2020 FOX News Network, LLC.

The recently detected FRB, known as FRB 180916.J0158+65, sends out bursts that last for four days before stopping for 12 days and then repeating. Every 16.35 days, the signal named FRB 180916.J0158+65 follows a similar pattern. According to Rajwade, the discovery “could argue against a precessing neutron star,” as the cycle, at 157 days, is far longer than the first repeater of 16 days. It's also possible that it could be coming from a binary star system, but more research is needed.It's unknown how common FRBs actually are and why some of them repeat and others do not; most of their Some researchers have speculated they stem from an extraterrestrial civilization, but others, including the Search for Extraterrestrial Intelligence Institute, or SETI, have said that explanation "really doesn't make sense. That changed when the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/FRB) discovered a repeating pattern. (Credit: NRAO Outreach/T. For four days, it will spit out a burst or two every hour. According to a new study, an FRB has been spotted coming from a galaxy 500 million light-years from Earth and it's repeating every 16 days. "They come from all over space "and arranging cooperative alien behavior when even one-way communication takes many billions of years seems unlikely — to put it gently," SETI wrote in a First discovered in 2007, FRBs are relatively new to astronomers and their origins are mysterious. “The found location is radically different from the previously located repeating FRB, but also different from all previously studied FRBs," said Kenzie Nimmo, a doctoral student at the University of Amsterdam, in a It's unclear what's causing the pattern to repeat, but the study's The FRB has been traced to a galaxy known as SDSS J015800.28+654253.0 and despite its great distance from Earth, at 500 million light-years, it is the closest FRB detected so far. According to the authors of the arXiv paper, the FRB produces several radio bursts per day for a period of four days, before falling silent for slightly more than 12 days.
Before now, such pulses appeared to be random in timing. A light-year, which measures distance in space, equals 6 trillion miles.It's possible the FRB could be orbiting a compact object, for example, a black hole, causing its pattern to repeat, the researchers added in the study. An animation shows the random appearance of fast radio bursts (FRBs) across the sky.

"While the cause of the repeating pattern is unknown, researchers said the FRB could be orbiting a black hole-like object, flashing its signal at a specific point in its orbital period.
