An alien explosion occurs unexpectedly and intrigues scientists

It is not new that the mysteries of the universe were surprising Astronomy scientists🇧🇷 From each new discovery, it is possible that a certain theory will be created, deepened or overthrown.

Article published by the magazine nature It was recently revealed that an international team of astrophysicists reported that they had detected a unique cosmic gamma-ray burst.

Surprisingly, such an event ends up questioning some hitherto dominant theories about how violent cosmic explosions form.

This explosion mentioned in the article ends up leading researchers to put forward a new model or source for some different types of GRBs (gamma ray bursts🇧🇷

Gamma ray bursts are the brightest and most violent explosions in the universe to date. They are caused by the death of stars or the collision of remnants of stars.

These eruptions generally fall into two categories: GRBs In the short and long term.

Long-lasting ones arise from the death of very massive stars and generally end up being associated with those phenomena that are visible for a very short period of time, such as, for example, supernovae🇧🇷

Short periods have a very short duration of only 2 seconds. These arose from the collision of two neutron stars or the collision between a neutron star and a Black holebeing, in general, associated with less acute visual phenomena, such as, for example, kilonovas.

For decades, all GRBs remained well suited to these categories, but that has now changed. This is because, on December 11 of the year 2021, the GBR ended up giving off many gamma-ray detectors scattered throughout space.

One of these detectors was the Fermi Gamma-Ray Space Telescope, as well as NASA’s Neil Gehrels Swift Observatory. The GRB produced scattering of signals to the detectors that lasted for approximately 70 seconds.

So, as you’ve already seen in this article, as the current model indicates, GBR will be long-lived.

However, it was noted by several follow-up observations by teams from the US and Europe, a kind of “signature” that turned out to be a surprising discovery.

Check out what a former student from Nevada (USA), Peng Zhang, who is currently at Nanjing University (China) and who was the author of the study in question, had to say:

“The GRB has two parts: a powerful 13-second peak and an extended, softer 55-second emission. The strong 13-second high duration should have completely ruled out this short GRB burst.”

Now check out what the study’s co-author and professor of astrophysics at the University of Nevada (USA), Ping Zhang, had to say about what this might mean:

“Such a strange GRB was the first of its kind ever. This discovery not only challenged our understanding of the origins of GRBs, but it also forced us to consider a new model of how some GRBs form.”
