For the first time in history: NASA observes gamma-ray bursts repeating from the same source!

In an unprecedented cosmic phenomenon that has puzzled astronomers around the world, a series of gamma-ray bursts _the strongest type of explosions known in the universe_ have been detected emanating from the same source within just one day, which challenges all existing hypotheses and scientific models.

The event, announced in an official statement from the European Southern Observatory, was described as "unprecedented" in the history of modern astronomy, as known gamma-ray bursts (GRBs) occur only once from each source, as they result from destructive events that do not repeat, such as the explosion of a massive star or its consumption by a black hole.

However, what happened this summer astonished scientists;

on July 2, the "Fermi" space telescope operated by the U.S. space agency ( NASA ) detected three consecutive flashes of gamma rays, emitted from the same location in the sky within just a few hours.

After analyzing the data, scientists discovered that the same source had shown radiative activity about a day prior, based on data collected by the "Einstein" telescope, which specializes in X-ray observations and is operated by China in collaboration with the European Space Agency and the Max Planck Institute in Germany.

The phenomenon was not just a rare repetition, but it was also highly energetic and long-lasting, as astronomer Andrew Levan from Radboud University in the Netherlands confirmed that this signal lasted "between 100 to 1000 times longer" than most known gamma-ray bursts, adding to its mystery and making its interpretation more complex.

Initially, scientists believed that the bursts might have occurred within the Milky Way galaxy, which would have made the event much closer to us and thus less strange.

But using the giant "VLT" telescope in the Atacama Desert of Chile, researchers were able to determine that the source might be located in another galaxy, billions of light-years away.

This hypothesis was later confirmed by the "Hubble" space telescope.

This vast distance means that the amount of energy emitted from the event was unusually immense, possibly exceeding any cosmic explosion documented before.

Dr. Antonio Martin-Carrillo from University College Dublin in Ireland, one of the participants in the study published in The Astrophysical Journal Letters, commented on the phenomenon saying:

"Theoretically, it is impossible for a gamma-ray burst to repeat from the same source, as the event that produces it is usually destructive and final. What we saw this summer completely contradicts this rule, making it unique compared to anything we have observed in the past fifty years."

As for the explanation of the event, scientists are still puzzled; some proposed scenarios include an unusual collapse of a very massive star, or perhaps the complete destruction of a strange star by an even stranger black hole.

But so far, there is no final explanation or scientific model capable of containing this event within the current understanding of astrophysics.

This astonishing discovery opens the door to reevaluating many concepts related to stellar death, black holes, and cosmic energy, and may reveal new types of astronomical bodies or physical processes that were previously unknown.

Scientists are racing against time to understand what happened, as these signals coming from the depths of the universe may carry secrets capable of changing our view of the nature of the universe itself.
