Radio signals from deep space repeated every 16 days

Scientists Detect Extragalactic Radio Signals Arriving in an Unexplained Pattern

In the study report of researchers, they say that these signals might come from a space body orbiting a star that sends a signal at a certain interval in its orbit.

Well, we might have a bit more of an answer thanks to a recent discovery.

The first repeating fast radio burst traced, FRB 121102, linked back to a small dwarf galaxy containing stars and metals.

This particular FRB is located in a star-forming region in a "nearby massive spiral galaxy". The CHIME/FRB researchers are publishing the details in a paper on the arXiv database.

This pattern was detected between September 16, 2018 and October 30, 2019 in fast radio bursts (FRBs) which are millisecond-long bursts of radio waves in space.

There was no mention of extraterrestrial life as a possibility for the radio bursts.

Researchers studying data from the radio telescope used by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) found the FRB signals arrived on Earth up to twice an hour for four days before suddenly stopping, only to start up again twelve days later.

But a new study which is conducted by an worldwide team of researchers which is led by a scientist at the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Bursts Project in the parts of British Columbia has now detected a mysterious FRB which comes from a galaxy that is located nearly 500 million light-years away.

Now, the evidence of a pattern in the signal adds to the question of what could cause these bursts to emit the way that they do.

During this time, the FRB 180916.J0158+65 followed a 16.35-day cycle.

In the paper, the researchers consider the possible causes, like the orbital motion of a star or an object that acts as a companion in the outskirts of the galaxy.

Neutron stars are the smallest in the universe, the remnants of supernovae. The combination of the interaction between the two, as well as the wind coming off of the OB-star, could be a factor in the cause of the repeating FRB pattern.

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

These signals, or fast radio bursts (FRBs), aren't unusual, but previous observations have shown them to be emitted totally at random.
