What Will Happen to the Sun? ☀️ From Giant Star to Tiny White Dwarf

In our previous video, we explored the white dwarf—the tiny, incredibly dense stellar remnant that the Sun is expected to become. But the Sun won't become a white dwarf directly. Billions of years from now, the hydrogen in its core will run low. Its core will contract while its outer layers expand dramatically, transforming the Sun into a red giant. 🔴 Mercury and Venus are expected to be engulfed, while Earth's ultimate fate remains uncertain. Eventually, the Sun will shed its outer layers into space, creating a spectacular planetary nebula. At its center, the exposed hot core will remain as a white dwarf. ⚪ With no ongoing nuclear fusion, the white dwarf will slowly cool over an unimaginably long period of time. From a stable star… to a red giant… to a tiny white dwarf. This is the incredible final journey of our Sun. 🌌
