In short: Despite its appearance, the Sun cannot be burning because fire requires oxygen—something absent in space. This video explains the actual physics powering our star.

The Sun functions as a massive cosmic engine powered by a mixture of hydrogen and helium gas. At its core, temperatures reach 15 million degrees, creating the heat and light necessary to sustain life on Earth.

To grasp its scale, consider that the Sun is large enough to fit approximately 1.3 million Earths inside it. The video clarifies these complex solar physics through simple animations for students and curious minds.
