Alien Messages? Mysterious Radio Signals from Galaxy Puzzle Scientists

Scientists have been puzzled with short bursts of cosmic radio waves called Fast Radio Bursts coming from an unidentified source in the space ever since the first one on record was detected in 2001.

The FRBs last just a few milliseconds but register about a billion times brighter than anything ever observed in the galaxy. The first fast radio burst Lorimer Burst FRB 010724 (Year/Month/Date format of recieiving the signal) was received on July 24, 2001 by the Parkes Observatory and several FRBs have been added since 2007.

The next major one was recorded on 19 January 2015 by astronomers at Australia’s national science agency (CSIRO), which was observed for the first time live, by the Parkes Observatory. The latest one was in April 2017.

Ruling out the possibility of our own terrestrial interference, Manisha Caleb of the updated Molonglo Observatory Synthesis Telescope (UTMOST), located about 350 km south of Parkes near Canberra, said the telescope could only detect transmissions originating beyond Earth’s atmosphere, from 10,000-km away, and hence they are not terrestrial.

The UTMOST is a 778-metre-long parabolic cylindrical antenna array with 352 independent antennae, 7,744 ring antennae that has enabled researchers to use the technique of interferometric detection to calculate the minimum distance of FRBs.

Led Professor Matthew Bailes, the revamped synthesis telescope is being used to help pinpoint the source of FRBs and its telescope has been fitted with a new supercomputer system enabling observations to be viewed in real time and the colossal 1,000 terabytes of data produced daily to be sifted and processed.

Manisha said her team has successfully identified the origin of three distinct FRBs. “The telescope has literally been reborn and transformed exclusively to search for these Fast Radio Bursts,” she said. “We have scientifically confirmed that FRB’s are extra-terrestrial.”

The puzzle is not on the source fo signals from the galaxy but the reason for such waves. Some scientists argue that they could be sounds emerging from colliding of stars in distance galaxy but claim that could be artificially created alien messages or extraterrestrial intelligence.

So far 22 FRBs have been detected but astronomers claim that anywhere between 2,000 to 10,000 FRBs could be emanating from the space every day.
