They capture an “exceptional cosmic explosion” caused by the birth of a black hole

NASA’s Swift and Fermi missions detected an unusual cosmic explosion. It is an unusually bright and long-lasting pulse of high-energy radiation that passed through the Earth from a gamma-ray burst, considered one of the most luminous events known.

Of agreement To the space agency, a burst of X-rays and gamma rays passed through the solar system on October 9, activating the detectors on board the Fermi gamma-ray space telescope and Neil Gehrels’ Swift observatory, so telescopes around the world They pointed to the power source.

As detailed by NASA, the explosion, called GRB 221009ª, originated in the constellation of Sagitta, located about 1,900 million light years from our planet. At the moment, astronomers estimate that it is the result of a new black hole, caused by a massive star that collapsed under its own weight.

When a black hole is born, experts explain, it drives powerful jets of particles that travel at a speed close to the speed of light and emit X and gamma rays as they go out into space.

The light produced by this explosion, the researchers point out, provides new insights into stellar collapse and the birth of a black hole, as well as the behavior of matter when traveling at speeds close to the speed of light.

The single trade union center of Uruguay (PIT-CNT) spoke out against a bill that is currently advancing in Parliament to modify the current legislation on collective bargaining between employers and workers. The initiative went to the legislature to respond to observations presented to the International Labor Organization (ILO). It is “an outdated and regressive proposal by a handful of businessmen,” says a statement from the Inter-Union Plenary of Workers-National Workers’ Convention signed by its president Marcelo […]
