This star will shine bright in the sky and became the second sun. Even so, some scientists argue it is nonsense.
"Betelgeuse soon lose mass and become a supernova. However, the 'immediate' in astronomical time scale means that one million years from now, "said University of Illinois astronomer Jim Kaler.
No one quite knows Betelgeuse. This star is 10-20 times larger than the sun and it will explode. If you do not explode, said Kaler, this star will form the constellation Orion's right shoulder and will not be a second sun in the sky Bumir.
"Supernova would like a crescent moon bright and clearly visible during the day. It would appear the shadows, may make people scared but not as bright as the sun, "Kaler said that the focus on the study of dead star since the 1950's it. He felt there was no reason to fear the explosion of a star.
When the star becomes a supernova, the explosion of a large amount of matter and radiation spread in space. If such events occur within 30 light years from Earth, this explosion will significantly damage Earth's ozone layer and cause mass extinctions.
A light year is the distance light travel in one year, about 10 trillion kilometers. Some supernovae produce gamma-ray burst radiation is strong and dangerous.
Betelgeuse is 600 light years away and too far away to threaten Earth. Betelgeuse explosion itself portrayed scientists as a Core-Collapse Supernovae Type II. Kaler ensure these stars do not produce gamma-ray burst.
So what will happen when Betelgeuse explodes? "The blast will make a mess Orion constellation," said Kaler.
