Telescope detects 100 mysterious radio signals from three billion light years away

10 September 2019

While astronomers have recently made some exciting progress in tracing FRBs, we just don't know exactly what these signals are, or how they originate.

The "fast radio bursts" were detected by the Five-hundred-meter Aperture Spherical Radio Telescope - also known as FAST - and are now being analysed to discover how they were generated, according to Chinese publication Xinhua.

China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST) has detected a repeating fast radio burst (FRB) - mysterious radio signals from outer space - for the first time, Science and Technology Daily reported. This information was given by China's official news agency Xinhua on Monday.

Fast radio bursts (FRB) are radio pulses lasting a few milliseconds whose nature is yet to be thoroughly studied.

Fast radio bursts, or FRBs, in short, are some mysterious signals that usually come from the distant Universe, from millions and even billions of light-years away from Earth. The first one was spotted in 2007, and we're finding more of them all the time. It is the world's largest filled-aperture radio telescope and the second largest single dish aperture.

Now that the significance of FRB121102 is fully apparent, FAST will be undertaking further monitoring of the burst, which is coming from a dwarf galaxy in the constellation Auriga, according to a 2017 article by CNN.

FAST latched on to FRB 121102 on August 30, before recording dozens of later pulses (on one particular day, September 3, more than 20 pulses were detected).

The capacity of the FAST facility is truly awesome thanks to its ultra-sensitive 19-beam receiver installed on the enormous telescope body.

The telescope's considerable observational power will be used by astronomers from various nations to study such phenomena as exoplanets, gravitational waves and ultra-high-energy cosmic rays.

Chinese researchers say they will continue to monitor burst from FRB121102 to gather as much information on the source of these pulses as possible.
