Astronomers are discovering mysterious signals from our galaxy


Astronomers have discovered mysterious and intense signals from within our galaxy, although these rapid radio bursts, or FRBs It lasts only a fraction of a second, but it can be a hundred million times stronger than the sun and, despite its intensity, its origin is still largely unknown, and now astronomers have detected a fast radio signal in our Milky Way for the first time ever. In addition to being closer than any other FRB Discovered earlier, they can finally help solve the mystery of their provenance.

According to the British newspaper The Independent, scientists have had a hard time tracing the source of such explosions because they are very short and unpredictable and originate very far away, but it is clear that they form in the most extreme conditions in the universe, with suggested explanations including everything from dying stars to technology. Space.

Scientists who discovered the signals said FRBs The new bursts of radio energy appear to come from a magnetic star, or from a star with a very strong magnetic field.

Kioshi Masoy, assistant professor of physics at the Massachusetts Institute of Technology, who led the analysis of L. FRB: “There is this great mystery as to what could produce these huge bursts of energy, which we have seen so far come from half the universe, and this is the first time we have been able to connect one of these strange rapid radio bursts to a single astrophysical object. ”

The discovery began on April 27, when researchers, using two space telescopes, captured many X-ray and gamma-ray emissions from a magnetic star at the other end of our galaxy, and the next day the researchers used two North American telescopes. to observe it. point of the sky and picked up the explosion that became known. Basim FRB 200428.

Besides being the first FRB From the Milky Way galaxy and the first to bind to a magnetic star, the explosion is the first to send out emissions other than radio waves.

The research is described in three articles published in a journal Nature Today, that was based on data taken from telescopes around the world, with an international team of scientists using observations taken from equipment in Canada, the United States, China and space.

discovered FRBs For the first time in 2007, it immediately sparked a flurry of speculation about what would have caused such intense bursts of energy.
