The first association we get about stars in our universe is the Sun. The sun is one of the biggest stars we see on a daily basis. But the Sun is just one of the many stars in the universe, and truth be told, it is not that much big when compared to other stars.
Stars like VY Canis Majoris, Antares, Pistol Star, Aldebaran, and others are bigger, and more luminous than the Sun. Yes, most of them sound like taken from a Star Wars or Star Trek movie. But they do exist.
For example, VY Canis Majoris is 4,900 light years away from Earth. And unlike many stars, Canis Majoris is actually a single star.
Scientists have always been amazed by stars. And even we, as society, have been exploring the stars long ago. Even in Ancient Times, philosophers were mesmerized by the stars in our universe.
