Scientists have been perplexed by "fast radio bursts" (FRBs) or blasts of radio waves from distant galaxies since they were first detected years ago.
The FRBs are usually about one-thousandth of a second, making it impossible to pinpoint their origins.
To date, almost all of the 85 detected FRBs are one-time events, but a few have repeated, allowing astronomers to locate one of them.
Now, researchers have located a second FRB. The team used an array of 36 radio dishes in Western Australia to pinpoint it.
Using some of the world’s largest telescopes, the FRB was identified as coming from a galaxy 3.6 billion light-years from Earth.
Science Magazine reports that astronomers have dubbed the newly located FRB as "FRB 180924".
