Astronomers have revealed the details of receiving a mysterious signal from a galaxy far away in the universe. The signal was captured by a Canadian telescope.
However, scientists have not yet been able to figure out the meaning of the signal or where it is coming from.
It contains 13 high-speed radio explosions, which are repeated over and over again. Scientists are describing it as FRB. The word comes from a source about a thousand and a half light-years away.
This has happened once more in the past, it was known through another telescope.
Ingrid Stears, an astronomer at the University of British Columbia, says: "Once we know this, there is an indication that there is something else in the universe."
"More and more of these words have been found, and as more sources for research are found, we may begin to understand the mystery of this creation - where it comes from and why it is being generated."
The Shaimi Laboratory is located in the Okanagan Valley, British Columbia, with four hundred-meter-long antennas, where the signal is detected. From this laboratory daily searches are carried out in the sky.
Since the telescope began work last year, it has heard the sounds of 13 cosmic explosions in the universe, one of which has returned several times.
The study was recently published in the journal Nature .
"We got a repetition of a signal for the second time, the second signal was exactly the same as the first," says Sriharsha Tendulkar of McGill University.
"It gives us a better idea of the properties of that signal," he says.
FRB means short but sharp radio waves, which are probably reaching the earth from the other end of the universe.
So far, scientists have been able to detect 60 single, high-speed radio waves, two of which have been repeated. Scientists believe that thousands of such radio waves are moving in the sky every day.
There are many theories as to why such radio waves are being created.
These concepts include: the rapid rotation of a neutron star with a strong magnetic field, the merging of two neutron stars together, and, according to a few observers, the waves coming from an alien spacecraft.
