Largest Stars Largest Stars in the Universe
In this vast universe, there are many stars scattered across various galaxies. However, not all stars are the same size. There is one star that is considered the largest star in the universe, namely the star VY Canis Majoris.
VY Canis Majoris is a red hypergiant star located approximately 3,900 light years from Earth. With a diameter approximately 1,800 to 2,100 times larger than the Sun, this star is incredibly large. Imagine, if our Sun were replaced with VY Canis Majoris, its size would reach as far as the orbit of the planet Mars in our solar system.
It’s not just the size that makes VY Canis Majoris special, but also the level of brightness. This star is one of the brightest stars ever discovered in the Milky Way galaxy. When viewed from Earth, its brightness can reach a magnitude of around -7.6, much brighter than Venus at sunrise or sunset.
However, even though it looks so bright, VY Canis Majoris is not a star that is easy to observe with the naked eye. This is because it is very far away and is located in the constellation Canis Major. Therefore, to study and observe this star, astronomers use telescopes equipped with advanced technology.
Apart from its size and brightness, VY Canis Majoris also has interesting characteristics. This star is in the final stages of its life cycle. In the next few million years, VY Canis Majoris will explode as a spectacular supernova. The debris from the explosion will play an important role in forming new stars in the universe.
However, even though VY Canis Majoris is very large and interesting to study, there are other stars that also deserve to be called the largest stars. Among them is Stephenson 2-18, which is also a red hypergiant star with a size almost the same as VY Canis Majoris. This star is located about 20,000 light years from Earth and has a diameter that is estimated to be about 2,150 times larger than the Sun.
While there are differing opinions regarding the largest stars in the universe, it is important to remember that a star’s size and brightness do not alone determine its greatness. There are many stars that are smaller in size but have interesting properties and characteristics, such as dense neutron stars or very hot white stars.
In conclusion, VY Canis Majoris and Stephenson 2-18 are the two strongest candidates for the largest star in the universe. However, due to the complexity of the universe and the limitations of current technology, it is difficult to determine which star truly holds this title. Perhaps, in the future, the discovery of new stars with larger sizes will provide humanity with new knowledge about the greatness and beauty of the universe.
