NASA’s Nel Gehrels Swift Observatory has picked up an unbelievable signal from the mysterious world of the early universe.
The unidentified object – the source of the signal – known as GRB210905A, has been around since the universe was about 1 million years old. Because it’s so far away, light from it takes 12.8 billion years to reach Earth, so what we’re seeing is not the present, but what existed in an explosive moment 12, 8 billion years ago.
According to Space, the scientists re-examined the ancient event by other powerful ground-based telescopes, including the Very Large Telescope and the Chilean Observatory La Silla. Europe (ESO).

The strange signal, in the form of gamma rays, appears only for a moment in the past. It was a super-powerful explosion that quickly died down.
Gamma radiation, which comes from certain types of nuclear collisions and nuclear decay of radioactive substances and gamma-ray bursts in the universe, known as GRBs for short, is a very rare and tinted event. secret.
According to research published in Astronomy and Astrophysics, astronomer Andrea Rossi from the National Institute of Astrophysics – Bologna’s Astrophysical and Space Science Observatory (INAF Bologna) – Italy thinks that the hypothesis is possible. Most likely, it’s still coming from matter being pulled in by a black hole’s massive gravity.
He also did not rule out the possibility that it came from a magnetic star – the type of intense neutron star that is the inert core of a dead massive star, but GRB210905A is too energetic to match a magnetic star.
To come to a final conclusion, scientists need to find more GRBs to compare and contrast, so super telescopes around the world still can’t prevent “sanding for gold”. For the newly discovered, anything emanating from such a distant and ancient world is a treasure that brings humanity closer to the secret of the early universe.
