The sudden noise of radio waves from the deep space keeps banging into radio telescopes on Earth, sprinkles those instrument detectors with surprising data. Astronomers are now using artificial intelligence (AI) to point out the sources of the noise, with the expectation to detail what is sending them to Earth, from the prospect of researchers, billions of light-years across the deep space.
Eventually, these unexplained and strange signals are detected only after never-ending researches, when they notice unrelated points in their data, sometimes years after the incident. These signals have unusual and complex structures, patterns of apex and valleys in radio waves, which play out in just milliseconds. It is not the type of signal astronomers anticipated to emerge from a single explosion or something of usual events known to scatter stakes of electromagnetic energy from the deep space. These mysterious signals are termed as fast radio bursts (FRBs) by astronomers. Ever since the first one was detected in 2007, with the use of data recorded in 2001, there has been an ongoing effort to identify their source.
However, FRBs arrive at random times as well as places, observation methods, and existing human technology are not enough to spot these uncanny signals.
And now, a team of research scholars said that they have managed to detect five fast radio bursts in real-time with the use of a single radio telescope. However, the origin and exact nature of the blasts of radio waves in unknown.
Among the thirteen recorded FRBs, there was a very unexpected repeating signal, appearing from the same source around 1.5 billion light-years away. Such an event was reported once before, by a distinct telescope.
The University of British Columbia’s Astrophysicist Ingrid Stairs has said, “knowing that there is another suggests that there could be more out there.”
Located in British Columbia’s Okanagan Valley, the CHIME Observatory consists of 400-meter-long semi-cylindrical antennas that have the potential to scan the entire northern sky on a regular basis.
It has detected thirteen FRBs almost immediately, along with the repeater.
Shriharsh Tendulkar of McGill University was quoted saying, “We have discovered a second repeater and its properties are very similar to the first repeater,” adding that “this tells us more about the properties of repeaters as a population.”
First Radio Bursts are bright and short flashes of radio waves. And so far, astronomers have detected nearly sixty single first radio bursts and thousands of FRBs in the sky. That are several theories regarding what would be causing them.
However, the exact reason for the strange noise is yet unknown. It can probably be a neutron star with a strong magnetic field, which is very frequently spinning, or two neutron stars that merge, and a minority of observers, some form of alien spaceship.
