A Mysterious Signal Detected From Space Caught on Earth, Researchers Are Confused

News24xx.com - Mysterious radio signals from outer space are caught repeatedly every 16 days, CNN.com reported.

For the first time, researchers saw the existence of these signal patterns.

The signal comes from one source which is half a billion light-years from Earth.

Fast radio bursts (FRB) are eruptions or bursts of radio waves for a thousandth of a second in space.

Between September 16, 2018, and October 30, 2019, researchers from the Canadian Hydrogen Intensity Mapping Experiment or the Fast Radio Bursts Collaboration Project detected a burst pattern that occurred every 16.35 days.

Then mysteriously for four days, the signal would release one or two explosions every hour.

Then, the signal will be silent for 12 days.

This finding was included in a pre-printed paper on arXiv.

That is, the paper has been moderated but not yet fully reviewed (peer review).

The authors of this paper are part of the CHIME or FRB collaboration, which has published many studies of rapid radio explosion in recent years.

This signal came to be known as a rapidly repeating radio burst, FRB 180916.J0158 + 65.

Last year, the CHIME or FRB collaboration detected the source of eight new fast recurring radio bursts, including this signal.

Repeated signals are traced to large spiral galaxies about 500 million light-years.

So far, researchers have tracked single and repeated radio waves back to different sources, which have deepened the mystery.

The first rapid repetitive radio burst to be tracked, namely FRB 121102, is connected to a small dwarf galaxy containing stars and metals.

Now, the pattern in the signal adds to the question of what might cause the bursts to radiate.

In the paper, the researchers revealed possible causes, such as the orbital motion of a star or object acting as a companion at the edge of a galaxy.

The authors of another paper, which consulted with researchers who discovered the pattern, thought that the cause might stem from neutron stars and early OB-type binary star systems.

Neutron stars are the smallest in the universe, supernova remnants.

Understanding fast radio bursts can also help astronomers learn more about the universe.

The researchers believe that future observations can help them determine whether other rapid repetitive radio bursts have a pattern as well.

That way, they will know whether this periodicity is a special moment or a mere regular behavior.

The researchers hope that by tracing the origin of this mysterious burst, they can find out what happened there and its causes.
