There are two “flavors” in the mysterious flash of radio lights.

Every two minutes, a mysterious flash of radio waves explodes somewhere in the sky and returns to darkness within a few milliseconds. Ten years have passed since astronomers first noticed bursts of archived data since 2007, carefully stockpiled examples of fast radio bursts (FRBs), and then searched for patterns that could reveal their origin. I spent a lot of time. Now they have a whopping 500 new bursts to study.

On June 9th, an international collaborative effort released the first Fed catalog from the Canadian Hydrogen Intensity Mapping Experiment (chime) In British Columbia, the number of known Feds has more than tripled in a single day. The new dataset strongly supports the notion that two different types of Feds are scattered in the sky of electric waves, and astronomers foresee the future of using the Feds to illuminate the farthest parts of the universe.
