When night comes, all we can see thousands of stars in the sky.The naked eye they look like each other.However, it is not.Astronomers have long proved that the universe no two stars.Each of them is different composition, color, strength of light, temperature, weight and other characteristics.
only one star from Earth seems particular - is the sun.It is located as close to the Earth.But in spite of this feature, the Sun has a tiny size compared to the other stars.For example, Eta Carinae weighs 100-150 of our Suns.
asking the question about what is the biggest star in the universe, one can not expect a clear answer.Outer space is not fully understood and is likely to explore every corner of the vast emptiness would be impossible.It is much more correct to ask, "What is the biggest star of all the known."
June 21, 2010 astronomers had detected light which has been given code R136a1.Today it is the biggest star of all the discoveries of science.Present this whopper can only find out what her weight - 265 solar masses!The brightness of its 8.7 million. Times more than the sun.From our system of planets R136a1 is so far from Earth that it will not be visible to the naked eye.
Modern technologies allow to measure the performance of the heavenly bodies, which are from us at a distance of millions of light-years.Thus, the temperature on the surface of the star R136a1 is more than 50, 000 ° K (Kelvin).Due to the high intensity of luminescence, the biggest star produces a huge level of stellar wind and a huge flow of your body release chemicals into the surrounding space.
According to the hypothesis of astronomers, all the stars with time reduced in weight.The biggest star of the universe has an age of 1 million. Years.During this time it has decreased in weight by one fifth.Accordingly, before it was even more.
biggest star was found with the help of the Hubble and VLT telescope.Her discovery was an incredible breakthrough in modern astronomy.Before that, it was believed that the stars have a mass of more than 150 solar masses, in principle, can not exist.But fresh discovery led to revise the current fundamental knowledge about the structure of the universe.So R136a1 could refute the theory of scientists astronomers.
Previously, the stars, reaching 150 solar masses, called supergiants.They were the largest in space.Star R136a1 has been assigned a new class - hypergiants.Scientists from the German Institute of Argelandera hypothesized that in the universe there are other hypergiants, and they appear from the merger of two supergiants.
According to astronomers, R136a1 - it is not only the largest and most heavy star, but the brightest of all.As stated above, the Sun dimmer it is almost 10 million. Times.
R136a1 How long will be the title of the greatest?Most likely no.Such it will remain for as long as the scientists will not open a new biggest star in the universe.And realizing the immensity of space and unpredictable, it is conceivable that before the next record there are not so long.
