Mysterious Radio Signal Picked Up From Unknown Source In Deep Space
Canadian scientists have picked up a mysterious radio signal sent by an unknown source in deep space. It lasted only a matter of milliseconds and it is the first radio signal received from the universe with a frequency below 700 MHz.
As a result, this signal is believed to be highly powerful.
The first radio signals were first discovered in 2007 and are known as FRBs (Fast Radio Bursts). They appear randomly which makes them both hard to find and study.
As it was reported by MailOnline, the signal was detected by a telescope that has been operating for less than twelve months. This telescope is designed to record signals between 6-11 billion years old.
According to Christopher Conselice, a professor at the University of Nottingham, the low frequency of these signals could be very helpful in identifying their source. The reason for their appearance could be exploding exotic stars, supernova, neutron stars at the center of distant galaxies or some other unknown physical mechanisms.
Scientists from the McGill University claim that these events can occur both during the day and night and their arrival time cannot be correlated with some known sources of terrestrial radio frequency interference.
Due to the short duration, it is difficult to identify the possible natural source of these signals, but scientists are still investigating to find out the source. The possible explanations include either advanced extra-terrestrial civilizations or exploding black holes and stars.
Dr. Mark Halpern explains that this event is a fundamental part of physics which is still a deep mystery. The occurrence of such events can actually help the scientists to understand how the universe started and what lies ahead.
