Found radio signals from space

Discover a team of astronomers A radio signal from another galaxy about 3 billion light-years away from Earth. This is the second time researchers have detected this strange signal. New fast radio blasts (FRB), better known as FRB 20190520B. The signal is located with a compressed and fixed e . radio source Associated with a high-quality star-forming dwarf host galaxy.

FRB . Detected Using the five hundred meters A spherical aperture radio telescope (FAST) in Guizhou, China in May 2019. Additional observations recorded approximately 75 more FRBs over five months in 2020. The signal was then translated using the US National Science Foundation’s Karl G Jansky Very Large Array (VLA). The results found that too The transmitting body was also responsible for the smaller and weaker radio bursts of FRBs.

Space, science has discovered new radio signals

These characteristics characterize the FRB 20190520B signal as being very similar to the first FRB found in 2016, FRB 12110. Researchers are still not clear what causes these FRBsbut they assumed the FRB was just born and has been signaling since then It is still surrounded by the dense material from the supernova explosion that left the neutron star. According to this theory, it is expected that The signals will gradually weaken as the FRB ages.

This type of field moves very quickly in this period and new discoveries appear monthly. However, many questions remain unanswered and the discovery unleashes great inspiring clues. More than a dozen FRBs have previously been located, five of which include frequent FRB sources. These discoveries, accelerated by technological advances in radio telemetry and astronomy, are allowing scientists to slowly gather More information about cosmic events such as the death of massive and supermassive stars and the merger of neutron and magnetic stars.
