Stars are massive sphere of plasma held together by gravity. As you know Earth’s nearest star is the Sun at the center of the Solar System. It has a diameter of about 1,392,684 km.However, compared to many of the other stars discovered in the Universe our central stars is very small. Some other stars are visible from Earth during the night, appearing as a multitude of fixed luminous points due to their huge distance. Historically, the most prominent stars were grouped into constellations, and the brightest stars gained proper names. The below is the list of top 10 largest stars known in the universe:
Scientists found mysterious hot spots in a red supergiant star. Astronomers submitted the photo of an external layer of the atmosphere of a Betelgeuse star. It is the red supergiant next to Earth. It is very bright star located in constellation of Orion, which is the semiregular variable star which shine changes from 0,2 up to 1,2 star sizes and on the average makes near 0,7m. Red color of a star is easily noticeable at supervision by naked eye. The new photo of this star opens secrets of structure of substance, which proceeds from a star. In the photo on the right is visible the Betelgeuse star and her orbital circles. The photo was made by the camera of a radio telescope of MERLIN of Jodrell Bank Observatory. The Betelgeuse star is in 1000 of times massive from our Sun, but at distance of 650 light years from Earth, it still looks as a small point. In spite of the fact that it is a cold pro-evolving star, scientists found on it strange hot spots.
Scientists make assured that there is no possibility that the Betelgeuse star will become a supernova and will explode someday soon.Betelgeuse is one of the brightest stars in the sky that lies some 430 light-years from Earth.
