In Just 47 Days, Scientists Detected 1,500 Unidentified Signals From Deep Space

By: April Carson

The largest collection of FRB events to date has been recorded by the National Astronomical Observatory of the Chinese Academy of Sciences (NAOC) in Nanjing, China. The team, led by Professor Li Di and Dr. Wang Pei, captured the fast radio bursts, which arrived in record time from just one unknown source in deep space.

Astronomers say more than 1,500 fast radio bursts have been discovered in the largest discovery yet

In 2007, researchers discovered the first of these signals. They are driven by a very strong burst of energy that lasts milliseconds. Until recently, FRB signals were considered to be rare, however recent observations suggest that many of them repeat on a regular basis.

It's a big deal that an international team of astronomers participated in the new research. It was dubbed FRB 121102, and it set several records at once. According to reports, on August 29, 2019, the FAST spherical radio telescope in NRAO recorded 1,652 fast radio bursts in just 47 days.

The most comprehensive collection of fast radio bursts to date

This is the most comprehensive database of FRB occurrences to date. The authors of the study state that it alone contains more FRB signals than were detected from all other sources combined.

FRB 121102 is the only source that produced repeated fast radio bursts.

The detection of such a large number of FRBs from this particular source might present an opportunity to detect this event in real time. This would allow astronomers to study the burst and its origins like never before, as well as make it easier for scientists to develop methods that could be used to trace back the source of FRBs.

Researchers hope that such a large packet set will allow researchers to analyze the characteristics of FRB signals, such as their spread and distribution. And the information obtained may be used to examine other similar signals in the future, which should shed light on the source of these enigmatic broadcasts.


The researchers emphasize that the FRB 121102 event is the first space 100 percent sure known repeating FRB that we have discovered. The signals were tracked and determined to come from a dwarf galaxy. The huge number of signals received from there suggests that something called a "permanent radio source" is located in this galaxy. Simultaneously, scientists do not exclude the possibility that FRB 121102 is caused by a "transient radio source".

"This discovery has to be seen as a total success – we have collected more than 1,500 new signals from deep space", says Jason Hessels (Jason W. Hessels), associate astronomer of the University of Amsterdam and researcher in the project. "This is very unique because we were able to track these signals to a source in the sky, unlike previous observations when astronomers found only an FRB and could not pinpoint its location."

Other Discoveries

By the way, this was not the only finding. Six more previously unknown FRBs were found as part of the Commensal Radio Astronomy FAST Survey, and one of them, according to researchers, may be a new "repeater" similar to the FRB 121102 event.

Let's assume that the FRB signals are only one-thousandth of a second long, but they are able to radiate energy equivalent to the solar radiation produced every year.

Do we have a clear idea of what fast radio bursts are?

Fast radio bursts have no obvious cause, although several theories have been proposed in recent years. Some theorists even included such an unusual element as alien activity into their models, but recent findings have debunked this hypothesis - the strange noises are of natural origin, according to scientists. And while they search for their sources, scientists are considering a variety of possibilities, including a neutron star, a black hole or a gamma-ray burst.

The majority of the signals that scientists have detected recently were recorded using the CSIRO Radio Telescope in Australia, but there are several other telescopes from around the world that echo with their messages. In February 2015, researchers also found another burst - FRB 150215 - which was captured using the Parkes Observatory in Australia, but also one recorded by the Arecibo Observatory in Puerto Rico before that.
