Is it Antares? That is a huge star. Also how does it get to be so big and how long till it goes supernova or is it going to go supernova?
I think, without knowing if any POP III stars are actually "observed", that the http://www.solstation.com/x-objects/pistol.htm" is thought to be the largest.vincentm said:Is it Antares?

The biggest star we currently know of is UY Scuti, located approximately 9,500 light-years away. It has a radius of about 1,700 times that of our Sun.
Scientists measure the size of stars by using a unit called the solar radius, which is equal to the radius of our Sun. They also use other methods such as spectroscopy and interferometry to determine the size of a star.
Yes, it is possible for stars to get even bigger than UY Scuti. However, the largest known stars are already approaching the theoretical maximum size that a star can reach due to the balancing forces of gravity and radiation pressure.
Scientists use a method called parallax to determine the size of stars that are far away. This involves measuring the apparent shift in a star's position when observed from different points in Earth's orbit. They can also use other techniques such as photometry and spectroscopy.
No, there are no stars that are bigger than our entire solar system. Our solar system is relatively small compared to other stars, with the biggest star, UY Scuti, having a radius of 1,700 solar radii. This is still much smaller than the estimated size of our solar system, which is about 100,000 astronomical units in diameter.
