They detect the first fast radio burst repeatedly and persistently active 3,000 million light years from our galaxy


Although little is known about the origin of this phenomenon, some scientists suggest that it could be evidence of advanced extraterrestrial life.

An international team led by Chinese scientists discovered and located the first repeatedly and persistently active fast radio burst (FRB) through the 500-meter-aperture spherical telescope located in southwest China. The results of their research were published this Wednesday in the journal Nature.

The device facilitates the study of the evolution of FRBs and can help astrophysicists to understand the origin of the brightest radio waves that emanate billions of light years away of the Milky Way. Thus, the new burst, named FRB190520B, is found in a dwarf galaxy located 3,000 million light years away.

This phenomenon consists of mysterious radio flashes that last for milliseconds and come from deep space, but little is known about their origin. However, some scientists suggest that could be evidence of advanced extraterrestrial life , details the Chinese newspaper The Global Times.

So far, less than 5% of all hundreds of detected FRBs have been seen repeatedly and only a few are active.

The behavior of the newly identified burst is similar to that of FRB121102A, the first FRB discovered, although the new one is persistently active and has a more complex electromagnetic environment, Niu Chenhui said. , a researcher at the National Astronomical Observatories of the Chinese Academy of Sciences, who located the unique phenomenon.

“We also postulate that FRB121102A and FRB190520B represent the early stage of an evolving FRB population,” said Li Di, the lead author of the study. “It is likely that within a few years a coherent picture of the origin and evolution of FRBs will emerge,” said the scientist.
