A blue star that is 2.5 million times brighter than the sun suddenly disappears for no reason.

According to the British”Metro” report on July 1, astronomers observed a”super blue star” in the vicinity of the Milky Way, which is said to be 2.5 million times brighter than the sun, mysteriously disappeared recently, causing the nearby galaxy to suddenly change. It was so dark that the scientists said that they were very strange.

This super blue star, located in the Aquarius constellation, is about 70 million light-years from the ground and is part of the Kingman Dorf galaxy. Scientists are not sure why the star suddenly disappeared, and two possible explanations are proposed. The first type is obscured by the light of stardust. The second type is more interesting, that is, the star collapsed into a black hole without undergoing a supernova explosion.

Dr. Andrew Allen of the Trinity College in Dublin led the study. He believes that if the star really disappeared due to the collapse, then”will be the first one we directly detected in this way Superstar that ends its life.” He also said,”It is uncommon for such a large planet to disappear without undergoing a supernova explosion.”

Researchers used giant telescopes in the Atacama Desert in Chile to observe the planet. In fact, at a distance of 75 million light years, astronomers can’t see its existence at all, but the researchers can verify the existence of the star by examining its unique chemical spectral information. They revealed that between 2001 and 2011, scientists discovered a”variable blue star” that is 2.5 million times brighter than the sun, but this state itself is unstable and may explode. And end their lives.

However, in 2019, astronomers will no longer be able to observe it, Dr. Allen said,”We were surprised to find that this star disappeared.” Another study by Trinity College in Turin The author José Gro said,”We may have observed that the largest star in the universe is plunged into a good night.”

Researchers said that more research work is needed to understand What happened to this star. Because if you do not create a supernova explosion and become a black hole, it will be an extremely rare event and may challenge the current theory of”how large stars end their lives”.
