The mystery of blue light explained three years ago in the sky

Astronomers were amazed when they saw bright blue light coming from a distant spiral galaxy about 200 million light years away, reports Independent.

The discovery of the event known as AT2018 occurred in June 2018 and was seen by the Hawaiian observatory, which soon sent a global message to others to look at their telescopes in a certain direction.

Scientists then saw a light that is 100 times brighter than the supernova, the most brilliant explosion mankind has ever seen.

It seemed to be a supernova, but it was much brighter and faster than in similar events.

Scientists have struggled to explain the phenomenon, which became known as the fast blue optical transition (FBOT), but without explaining how it happened.

Further discoveries made the event only confusing. Scientists have determined that it consisted not only of lighting but also of powerful pulses and X - rays, with hundreds of millions of pulses leading to the source itself.

The pulses were repeated regularly, every 4.4 milliseconds, for 60 days. Scientists used these pulses to estimate that X - ray radiation must be no more than 1,000 miles [1,000 km] wide and have a mass less than 800 suns.

This indicated that it was compact, such as a small black hole or a neutron star. Mystic light appears to have occurred at the time of the star's death as it collapsed and a black hole arose. It began to <x0ha” the substance around it, swallowing the star, releasing strong energy waves.

This is the conclusion presented in Nature Astronomers magazine.

“We may have discovered the birth of a solid object in a supernova. That happens in normal supernova, but so far we haven't seen it because it's a very chaotic process. We think this new evidence opens up the possibility of finding a black hole or a neutron star”, said lead author of the article Diray Pasham, a researcher at the Massachusetts Institute of Technology in Cambridge.
