Scientists have identified the source of a repetitive radio signal, one of the most remarkable cosmic events of recent years.
As scientists continue their studies on space, they occasionally reach surprisingly mysterious findings.
From time to time, astronomers discover radio signals from deep space and investigate the source of these signals.
Scientists have identified the source of a repetitive radio signal, one of the most remarkable cosmic events of recent years.
Signal comes from dwarf galaxy
First detected in 2019 and called FRB 190520, the radio signal was understood to come from a dwarf galaxy 3 billion light-years away.
It is known that about 5 percent of the hundreds of detected signals are repeated. FRB 190520 is the only signal that has remained active since its discovery.
Astronomers have been able to follow such signals back to where they came from before. But what produces them is still a mystery.
So learning more about these bright radio emissions could help scientists understand what’s producing them.
Trying to find out where FRB 190520 came from, researchers used the Subaru Telescope and the Very Large Telescope in Hawaii.
