Scientists have said that the explosion, which occurred at a distance of 180 million light-years from Earth, could change the existing ideas about how stars die.. It became the "

The explosion, known as AT2018cow, belongs to a rare class of cosmic explosions known as fast blue optical transients, or FBOTs.. But, unlike other similar events, for some reason the explosion occurred only in the side. Because of this, its shape does not resemble a ball, but a disk..

“Very little is known about FBOT explosions - they just don't behave like stars should explode, they're too bright and evolve too fast.. Simply put, they are strange, and this new observation makes them even stranger,” said lead author of the study, astrophysicist Justin Mound from the University of Sheffield in the UK..

“Hopefully this new discovery will help us shed a little more light on them – we never thought that explosions could be so aspherical.”. There are several possible explanations for this: the stars involved could have created a disk just before they died, or they could have been a failed supernova where the star's core collapses into a black hole or neutron star, which then eats the rest of the star,"

AT2018cow, nicknamed " The explosion was very bright, so much so that initially scientists thought it was much closer to us.. It looked like a normal supernova explosion, but later astronomers found that it was 10 times more powerful..

The " Although at the moment there are assumptions explaining the nature of such explosions, there is no unambiguous idea of \u200b\u200bwhat causes them.. Therefore, scientists continue to study the data obtained from such explosions..

In the course of the study, Mound and his colleagues examined data on the polarization of the Cow obtained using the Liverpool Telescope. This polarization was extremely high and was recorded at several wavelengths several times during the first night of observations after the explosion, and then in the following days.. This allowed the researchers to reconstruct the 3D shape of the explosion.. Curiously, at the 12-day mark, they observed a "

It was this polarization profile that prompted scientists to think about the unusual shape of the explosion..
