Chinese Astronomers Spotted Puzzling Fast Radio Bursts From 3 Billion Light-Years Away

Now FAST, located in a naturally deep and round karst depression in southwest China's Guizhou Province, has also detected multiple eruptions from FRB 121102, thought to be located in a dwarf galaxy about three billion light-years from Earth.

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.

The FAST team were studying a fast radio burst source known as FRB121102, first spotted in 2015.

Experts at the Chinese Academy of Sciences are now analysing and cross-checking these signals to try and understand more about where they come from.

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.

Now, according to the Chinese Xinhua news agency, the fast radio bursts detected by the Chinese astronomers might shed more light on the mechanisms of mysterious signals and their origins.

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

The 19-beam receiver on FAST is especially sensitive to radio signals, covering the 1.05-1.45 GHz frequency range, and that makes it flawless for keeping an eye on FRB 121102.

As the Chinese scientists reported, FRB121102 is now more active than ever.

The Chinese telescope, FAST, is very powerful, and its purposes go beyond identifying fast radio bursts. They have proposed ambitious observation objectives for the telescope, such as gravitational waves, exoplanets, ultra-high-energy cosmic rays and interstellar matter to advance human knowledge of astronomy, astrophysics and fundamental physics.
