First Contact? Something in Space is Sending Earth Signals Like Clockwork, Scientists Don’t Know Why

Astronomers from around the world have long been fascinated by the mysterious radio signals bombarding our planet from deep in outer space, with some onlookers linking them to a possible extraterrestrial intelligence.

A new study by an international team of scientists led by astronomers at the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/FRB) in British Columbia has discovered that a mystery radio source in a galaxy some 500 million lightyears from our solar system is sending out fast radio bursts like clockwork in 16.35 day cycles, including 1-2 bursts per hour over a four day period and then 12 days of silence before starting up again.

The mystery signal, known as FRB 180916.J0158+65 was first discovered in 2017, but has continued repeating steadily, albeit at a rate some 600 times fainter than the first bright flare. In their study, scientists analysed 28 bursts which took place between September 2018 and October 2019, confirming the pattern, and excitedly concluding “that this is the first detected periodicity of any kind in an FRB source.”

The new FRB was tracked down to SDSS J015800.28+264253.0, a star-forming galaxy about 500 million light years from Earth.

And although the scientists don’t mention it, there’s no ruling out that this could be an alien life-form attempting to make contact with other lifeforms in the galaxy. Human scientists have been fascinated with the concept of using radio waves to try to make contact with extraterrestrial intelligence since the 1890s, and countries have built a number of radio telescopes over the past century to listen out for incoming extraterrestrial radio waves.

The study’s authors now plan to continue watching out for the signal-emitting object, looking out for clues regarding its origins. Scans of SDSS J015800.28+264253.0 by X-ray and gamma-ray radiation telescopes may provide further clues as to its identity.
