A gamma-ray burst is a large-scale cosmic burst of energy of an explosive nature, currently observed in the
The duration of this outburst, as scientists previously believed, depended on the type of object that generated the gamma-ray burst.
However, in the new work, the authors found that this was not the case when they discovered the GRB 200826A gamma-ray burst, which was generated by a large star, but lasted for a record short time.
There are two types of gamma-ray bursts, one lasting longer than two seconds and the other much shorter.The latter are produced by the merger of binary stars, while the former are produced by collapsars, large aged stars.We found that the collapse flare of GRB 200826A lasted less than a second.

Authors believe the surge was so shortdue to the fact that the plasma beams dispersed by the black hole were not strong enough to quickly break through the so-called cocoon of gas and dust that arises around old large stars in the last stages of their life. As a result, most of the energy of these emissions of matter was scattered inside this gas and dust shell.
Now, astronomers will revise their assumptions about what gave rise to other previously known gamma-ray bursts.
