This strange space phenomenon was discovered in 2007. Since then, scientists still can't explain what this burst of electromagnetic waves Fast Radio Burst, also known as fast radio cracking is due to. Pretty serious assumptions were made, as a consequence of the evaporation of a black hole, to the most extravagant hypotheses, such as the emitting of an alien signal.
The phenomenon was extremely difficult to explore as it lasted only one thousandth of a second. Until now, such impulses were considered to come only from other galaxies. The last most precisely recorded were in 2016 and came from a dwarf galaxy located 3 billion light-years from Earth.
On April 28, a Canadian study with the new CHIME telescope and the American Observatory “STARE-2" registered a similar momentum in the same area from the sky. The source turned out to be the magnetar SGR 1935+2154, located in our Milky Way.
"This is the first fast radio crack attributed to a familiar space object,” pointed out Christopher Bochenek from the US Kaltek Institute and project manager “STARE-2".
Magnetars are magnetic neutron stars with an extremely powerful magnetic field - one quadrillion times stronger than ours.. These objects are small in size - several tens of kilometers, but contain a significant mass. One teaspoon
of their matter would weigh several billion tons. The celestial lamp rotates around its axis for a few seconds.
The rapid radio pulse detected by scientists emitted in one millisecond as much energy into a radio signal as the Sun would need in half a minute, says Bocenek.
This signal was powerful enough to be traced with the receiver of a smartphone after passing through half the galaxy. One distance estimated at 30,000 light-years.
Scientists: We received a mysterious radio signal from inside our galaxy
Astrophysicists identified for the first time a magnetar from our galaxy as the source of rapid radio pulses, France Press reported.tags:
