A newly discovered example of this transient phenomenon has been traced to its place of origin — a nearby spiral galaxy — but it's only made things murkier for astronomers.</em></span></div><div style="text-align:justify;"><br /><em><span style="font-family:georgia, 'times new roman', serif;">The problem concerns a class of blink-and-you'll-miss-them heavenly events known as fast radio bursts (FRBs). In a few thousandths of a second, these explosions produce as much energy as the sun does in nearly a century. Researchers have only known about FRBs since 2007, and they still don't have a compelling explanation regarding their sources.</span></em></div><div style="text-align:justify;"><br /><em><span style="font-family:georgia, 'times new roman', serif;">"The big question is what can produce an FRB," Kenzie Nimmo, a doctoral student at the University of Amsterdam in the Netherlands, said during a news briefing on Monday (Jan. 6) here at the 235th meeting of the American Astronomical Society in Honolulu, Hawaii.</span></em></div><div style="text-align:left;"> </div><div style="text-align:justify;"><br /><em><span style="font-family:georgia, 'times new roman', serif;">FRB 180916.J0158+65, as the object is known, is a repeating FRB discovered by the <a href="https://www.livescience.com/63254-mystery-frb-detected-canada.html" target="_blank">Canadian Hydrogen Intensity Mapping Experiment</a> (CHIME) observatory, a radio telescope near Okanagan Falls in British Columbia that Nimmo called "the world's best FRB-finding machine."</span></em></div><div style="text-align:justify;"><br /><em><span style="font-family:georgia, 'times new roman', serif;">Follow-up observations by a network of telescopes in Europe allowed the research team to produce a high-resolution image of the FRB's location. This location turned out to be a medium-sized spiral galaxy like our Milky Way that is surprisingly nearby, only 500 million light-years away, making it the closest-known FRB to date.
