The Birth and Death of the Sun

The Sun's life begins as a cloud of gas and dust collapses under gravity, forming a hot core that ignites nuclear fusion, creating our star. Over billions of years, it steadily burns its hydrogen fuel, shining brightly. In about 5 billion years, it will run out of hydrogen, expand into a red giant, and shed its outer layers, forming a planetary nebula. Ultimately, it will become a dense, Earth-sized core called a white dwarf, gradually cooling and fading away. This process – from birth to its end – reflects the natural lifecycle of stars like our Sun driven by nuclear fusion and cosmic evolution.
