Mysterious radio signal from space flashes on Earth 2,000 times in 2 months – the Irish Sun

POWERFUL signals are being beamed toward Earth from space at an unprecedented rate.

According to scientists, a repetitive high-speed radio burst source discovered last year was recorded firing more than 1,800 shots in our direction over a two-month period.

The hyperactive nature of the outburst allowed researchers to pinpoint its host galaxy and source.

Called FRB 20201124A the object was discovered with the Five-Hundred-Meter Aperture Spherical Radio Telescope (FAST) in China.

It was described in an article led by astronomer Heng Xu of Peking University in China.

Fast Radio Bursts or FRBs are a mysterious space phenomenon.

The high-intensity emissions typically last only a fraction of a second, and their origin was unknown until recently.

Several thousand have been caught by scientists since it was first discovered in 2007.

All FRBs are unusual, but the newly discovered one was particularly odd.

Over 82 hours of observations spread over two months, FAST detected 1,863 outbursts, according to the article published in Nature.

Its polarization and signal strength varied wildly, making it the first FRB to show these types of variations in its waves, said study author Fayin Wang of Nanjing University Vice versa.

The evidence so far suggests its source is a magnetar, a neutron star with a strong magnetic field.

However, the way its polarization changed over time suggested that another object might be contributing to the signals.

“These observations brought us back to the drawing board,” said astrophysicist Bing Zhang of the University of Nevada at Las Vegas.

“It’s clear that FRBs are more mysterious than we imagined. Further multi-wavelength observation campaigns are required to further unveil the nature of these objects.”

Almost all FRBs discovered so far have come from too far away to clearly identify their origin.

Only a handful has repeated, and even fewer in a predictable pattern.

This makes them notoriously difficult to study, meaning their origins have eluded scientists for over a decade.

The signals are believed to come from huge explosions in deep space that fade away in less than a second.

In 2020, researchers said they had located radio flares emanating from an object known as a magnetar.

Magnetars are a type of neutron star with an enormously strong magnetic field – only a handful of them are believed to be in the Milky Way.

Physicists have previously speculated that magnetars could produce FRBs, but there was no evidence that this was the case.

That means the signals are not from extraterrestrial civilizations, a theory touted by some UFO hunters but rejected by scientists.
