Only on September 3, the equipment detected 20 radio pulses!
Chinese astrophysicists studying fast radio bursts (FRB — Fast Radio Bursts) have reported dozens of new signals. They were discovered using a radio telescope with a diameter of 500 meters, known as FAST.
The signals come from a dwarf galaxy, supposedly 3 billion light-years from Earth.
According to experts from the Chinese Astronomical Observatories at the PRC Academy of Sciences, the recorded FRBs have already been observed previously. A radio pulse, known as FRB121102, was first detected in 2012 and repeated in 2015.
In 2019, scientists spotted another impulse FRB121102 on August 30. After that, the telescope recorded dozens of repeating signals over several days. Only September 3 there were more than 20!
A fast radio pulse is a single signal from space lasting several milliseconds, which, according to calculations, is able to overcome intergalactic distances.
Scientists disagree on explaining the nature of signals. FRBs were first discovered in 2007, and among the hypotheses about their origin was a version about the alien nature of the signals. However, there is no definite answer: for example, in 2010, signals from the Earth were mistaken for FRB.
