Neutron stars can bounce radio waves to Earth

An international group of scientists uses the Green Bank telescope in West Virginia, USA, and the William E. Gordon telescope in Puerto Rico to study radio frequency (FRB).

The international scientists' finding could be the source of the Earth's emission.

An international group of scientists used in West Virginia, USA, and the William E. Gordon telescope in Puerto Rico to study radio frequency (FRB). They confirmed that the source of the flash was an extreme environment between the highest magnetic spaces, the International Business Times reported yesterday.

Astronomers use the term flash to refer to the inexplicable sources of origin far away. Although they exist in extremely short time, lasting only a few milliseconds at most, these flashes are powerful enough for researchers to detect them in the universe.

A source of lightning is, located in the dwarf galaxy 3 billion light-years from Earth, especially attracting attention because this is the only repeating flash. Scientists have discovered more than 200 high-energy carrier waves from there, but still cannot explain exactly what causes them to form.

Extremely strong magnetic fields usually only appear around black holes and at the center of galaxies, but FRB can be explained through a combination of other astrophysical conditions.

Based on data on FRB, scientists believe that they could come from a highly magnetic neutron star called magnetic star, located near a supermassive black hole with a mass of 10-100 million times the Sun and produces extremely strong magnetic fields or extracts hot gas. The study results are published in the journal Nature.

According to scientists, the length of radio waves is in the range of 30 microseconds to 9 milliseconds, indicating the source can be 10 km wide, equivalent to the size of a normal neutron star. Neutron stars are the collapsing core of larger stars that once had 10 to 29 times the mass of the Sun. They are the smallest and most dense stars known.

However, this hypothesis still does not explain many factors."At this point, we don't really understand the mechanism. There are many questions like how can a rotating neutron star produce the high energy levels commonly found in FRB?" , scientist Vishal Gaijar of SETI Research Center at the University of California, Berkeley and, two organizations that specialize in finding signs of alien intelligence, said.

Another possible explanation is that the word star may interact with a physical cloud originating from the original dead star. However, the researchers did not completely eliminate the possibility of lightning coming from an advanced alien civilization.
