The biggest star in the universe

What star ever open the most? Hard to say, because even with all the modern miracles of technology scientists are still difficult to judge the size of celestial bodies. However, the biggest star in the universe is now recognized by VY in the constellation Canis major. Its size was recently found. Did this Professor of the University of Minnesota Robert Humphrey. The calculation results are impressive: the star was around 1540 times more than the Sun. This suggests that if the star positioned at the place of the Sun, it would be fully closed orbit of Saturn. To enable readers to imagine VY Canis major (or, in scientific language, Canis Majoris) is large, we compare it with the Earth. In order to orbit our planet on a plane, going from 40 to 50 hours, and to fly around the largest star will have to spend about 1100 years.

VY Canis Majoris and Sun

Under the assumptions of the famous scientist Robert Humphrey, the surface temperature of a star of about 3500 degrees Kelvin. While the temperature on the surface of one of the brightest stars in the Universe is called ETA Carinae, is 25 thousand degrees on the Kelvin scale. Professor Humphrey believes that the size of the star depends on its temperature: the colder, the more. From this theory it follows that if there was a huge star with a temperature of 3000 degrees, the size it would be at 2600 Suns. And, according to Robert Humphrey, is the largest possible size for a star.

VY in the constellation Canis major

The first VY Canis Majoris were observed by Joseph jérôme de Lalande. The first mention of it in recorded observations date back to March 7, 1801. Also, based on his records, we can conclude that this star began to lose its brightness in 1850.

Scientists estimate VY Canis Majoris today has lost half of its mass. Consequently, the reserves of hydrogen fuel inside it is gradually exhausted. However, it may take more than one thousand years before, a massive star in our Universe explodes and forms a neutron star, and perhaps even a black hole. In any case, the inhabitants of the Earth have nothing to fear: the star is at a distance of 5 thousand light-years and its explosion will not cause us any harm.

However, it is one on one only of those heavenly bodies known to mankind. The universe is huge and as we would like, it is unlikely we will be able to thoroughly explore every area. Don’t rule out the possibility that somewhere beyond our reach is the star several times larger than VY Canis Majoris.
