New, mystery radio signals could be ‘extraterrestrial transmissions’

“…Perhaps the most bizarre explanation for the FRBs is that they were alien transmissions…” suggests a scientist behind the new study—accepted for publication in Monthly Notices of the Royal Astronomical Society.


The discovery of a new set of radio signals confirms that these mysterious ‘Fast Radio Bursts (FRBs)  originate outside our planet and even our galaxy.

One of the greatest mysteries of the universe—for modern scietnists—are the so-called Fast Radio Bursts. So far, no one has been able to successfully explain what or who in the Universe is transmitting short bursts of radio energy across the cosmos?

Rare, mysterious radio waves have baffled astronomers since the first time they were detected a decade ago. While no one can say for certain what these mysterious signals are, there are some who believe the mystery bursts may be a sign of advanced alien civilizations trying to contact us.

Now, a team of astrophysicists have confirmed that the mysterious Fast Radio Bursts (FRBs), which are intense bursts of radio energy that last a few milliseconds, originate outside our planet. According to the official website of Swinburne University of Technology (Melbourne, Australia), which led the study, the signals may even come from beyond our galaxy.

FRBs are basically radio emissions that appear temporary and totally randomly which makes them extremely hard to find, and even harder to study.

There are several theories as to what they might be. Some suggest they originate as stars collide, while others have ventured out saying that they may be messages from our cosmic neighbors.

Professor Matthew Bailes from the Swinburne University of Technology in Melbourne who participated in the new research said: “Perhaps the most bizarre explanation for the FRBs is that they were alien transmissions.

Manisha Caleb, an astrophysicist at the Australian National University (Canberra), explained that “discovering where those bursts come from is the key to understanding what originates them. Only one of the FRBs has been linked to a specific galaxy.”

Using the Molonglo radio telescope, experts from the Australian National University have detected three new FRBs. Precisely this telescope could help experts solve the mystery surrounding FRBs.

Because of the unique architecture of the Molonglo radio telescope, experts suggests it is an ideal tool to pinpoint FRBs thanks to its gigantic focal length.

Dr. Chris Flynn from Swinburne University of Technology who also participated in the study said: “Conventional single dish radio telescopes have difficulty establishing that transmissions originate beyond the Earth’s atmosphere.”

According to an article from Swinburne University, the Molonglo telescope has a huge collecting area (18,000 square meters) and a large field of view (eight square degrees on the sky), which makes it excellent for hunting for fast radio bursts.

Ms. Caleb’s project was to develop software to sift through the 1000 TB of data produced each day. Her work paid off with the three new FRB discoveries.
