Astronomers detect more mystery radio bursts from beyond the Milky Way


Sure enough, astronomers have discovered even more of those mysterious fast radio bursts from outside the Milky Way galaxy.


Each of those bursts represents about 25 million times more energy than the Sun, and they were collected at the lowest frequencies yet (400MHz to 800MHz).


The scientists recorded the bursts during a three-week period between July and August of 2018 while CHIME was still in a "pre-commissioning phase."


The project wasn't yet living up to its full potential, suggesting that there are plenty more bursts to be discovered.


They could be the result of magnetars, or rapidly spinning neutron stars that have been strongly magnetized.


The University of Toronto's Cherry Ng also told CNET that evidence of "scattering" (the effect of electrons and magnetic fields on the bursts' long journey) could help pinpoint their origins.
