mysterious series of fast radio bursts may have been twisted by extreme environment

astronomers watching a fast-radio burst flashing from more than 3 billion light-years away say that its source lies in an extreme environment with a powerful magnetic field — perhaps a supermassive black hole, or the remains of a supernova.the findings about the phenomenon known as frb 121102, described in the journal nature and at the american astronomical society meeting outside washington, hint that this mysterious source of powerful radio waves whose origin has puzzled scientists for years may finally be revealing its secrets.since their discovery in 2007 from older archived data, fast-radio bursts have confounded astronomers. these bursts last only milliseconds, shorter than the blink of an eye, but in that tiny moment they are incredibly bright, a sign that whatever caused them was very powerful.“it’s some sort of extreme physics that causes this emission and so the goal is to understand that,” study coauthor betsey adams of astron, the netherlands institute for radio astronomy, said at a briefing wednesday.the problem is that these bursts each only happen once — leading scientists to suspect that these were cataclysmic, death-throe explosions. so even if a telescope is lucky enough to catch one in the act of going off, there no way to go back to the same source for more detailed measurements.frb 121102, sitting about 3 billion light-years away in a dwarf galaxy, was different. since its discovery in 2012 it has repeatedly sent out flashes of radio waves, allo...
