Space: Astronomers discover 'alien' radio signals repeating on a 16-day cycle

Scientists Detect Extragalactic Radio Signals Arriving in an Unexplained Pattern

Scientists Detect Extragalactic Radio Signals Arriving in an Unexplained Pattern

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.

The powerful, high energy bursts are some of the most enigmatic phenomena in astronomy.

New research published in a Arxiv paper shows that scientists have found a regular signal pattern for one particular fast radio burst.

A signal called FRB 121102 was captured in 2012 by the Arecibo Observatory in Puerto Rico.

USA Today reported that The series of so-called "fast radio bursts" - which are very short-lived pulses of radio waves that come from across the universe - were detected approximately once an hour for four days and then suddenly stopped, only to start up again 12 days later.

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.

The authors of the paper are part of the CHIME/FRB Collaboration.

There is one source most scientists have generally ruled out: aliens. And usually when they repeat, it's sporadic or in a cluster, according to previous observations.

Since it was the discovery in 2017, the signals have repeated steadily, and now it adds up the mystery quotient surrounding this FRB.

The Canadian Hydrogen Intensity Mapping Experiment during construction of the parabolic trough reflector at the Dominion Radio Astrophysical Observatory in British Columbia, Canada. They occurred every 16.35 days from a source 500 million light-years from Earth, in the outskirts of a "massive spiral galaxy". In such a scenario, the signals would cease when they are obstructed by the other body. But that still doesn't explain how the signals were being sent out on such a regular basis.
