It doesn’t solve a mystery but potentially creates a new one.. or ones..
One of the fast radio bursts appears to have come from the chaotic, magnetically active environment near a type of dense neutron star called a magnetar. Meanwhile, the other fast radio burst, which scientists observed pulsating over the course of several months, came from the outskirts of a distant dead, star-starved galaxy.
Researchers utilized a fast radio burst-hunting machine called CHIME, or the Canadian Hydrogen Intensity Mapping Experiment radio telescope, to uncover both bursts. The instrument has enabled the detection of thousands of FRBs since 2020.
