Astronomers detect mysterious radio signal coming from 3 billion light-years away

Astronomers detected a radio signal coming from another galaxy, which happens to be nearly 3 billion light-years away from Earth.

However, this is not the first time that such a thing has happened. Once earlier, such a repeating signal was detected by scientists. The findings have been published in the science journal Nature.

The researchers have detected a new Fast Radio Bursts (FRB), which has been termed FRB 20190520B. As per the researchers, the signal was “co-located with a compact, persistent radio source and associated with a dwarf host galaxy of high specific-star-formation.” The discovery was made using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in Guizhou, China, in May 2019.

As per several observations, the emitting object was responsible for emitting smaller radio bursts between the FRBs.

Sarah Burke-Spolaor, co-author of the study, in an official statement said, “The FRB field is moving very fast right now and new discoveries are coming out monthly. However, big questions still remain, and this object is giving us challenging clues about those questions.”

The researchers have theorised that the FRB 190520 may be a “newborn,” meaning, it is “still surrounded by dense material ejected by the supernova explosion that left behind the neutron star.” The theory states that once the material dissipates, the burst signals will also decline.
