Biggest Known Star in the Universe
The stars may seem tiny when we are looking up the sky but some are larger than the earth. With the efforts of the experts, there have been a lot of instances when these stars are measured in order to determine the one with the smallest and the largest size. In this section, you will find the different details about the biggest known star in the universe.
NML Cygni, which is also known as the V1489 Cygni is on the post of the largest star that is currently known in the whole universe. This is considered as a hyper giant star. As it is being taught in every science subject, a star with this type of classification is known to have enormous amount of mass and luminosity. If you are going to compare it to the sun, you will find out that NML Cygni is largest for about 1,650 times when it comes to the radius. With its size, it can fill up almost half of the gap between Jupiter and Saturn when included in the solar system.
This largest found is estimated to be 5,300 light-years away from the earth. And if you were going to compare it to different ones under the category of hyper giants, you would determine that it is extremely luminous. It is known to have a dusty environment around it. Technically, it is a cool and highly luminous hyper giant star.
If you are thinking about the name and where it came from, the group who discovered the star gave it. Neugebauer, Martz and Leighton discovered the biggest star in 1965. The name of it was derived from the initials of the ones who discovered it. According to the observations that were done since its discovery, it has two discrete thick enveloped that are optical. These thick envelopes are composed of dust and molecules. The high rate of mass emission and the wind velocity are the factors that resulted to the formation of dust envelopes. Another thing that affected it is the fact that it is one of the stars that are experiencing the largest rates of mass loss per year.
In 1968, it is discovered that NML Cyg is rich in oxygen. This is something that is unique and extraordinary for a star. It also contains SiO, CO, HCN, CS, SO and other elements. These different elements are revealed after different observations that were made in the different years that passed after its discovery.
Every one has its own unique value and size. Sometimes, they can only live for few hundred years and there is no certainty when it comes to the temperature that they have in their atmosphere. Just like NML Cyg, many of them have extended atmosphere that is mostly covered in dust and other particles. According to the experts, there is no star in the solar system that is 1,500 times larger than the sun. And stars that are exceeding the limit luminosity and temperature are not ending well because they experience eruption.
