THE SUN

The Sun, a massive celestial body composed of gas and plasma, is primarily made up of around 91% hydrogen gas. As a result of the intense heat and gravitational force within the Sun's core, hydrogen atoms are fused together to form helium in a process known as nuclear fusion.

Due to the extreme temperatures present on the Sun, the plasma possesses an enormous amount of energy, enabling the charged particles to break free from the star's gravitational pull and emanate into space. This outflow of charged particles is referred to as solar wind. In certain circumstances, when this solar wind comes into contact with Earth's atmosphere, it may lead to the formation of auroras, such as the Northern Lights.
