Our Sun will not explode as a supernova.
Billions of years from now, after exhausting the fuel needed for nuclear fusion, the Sun will shed its outer layers into space. What remains will be its incredibly hot, dense core—a white dwarf. ☀️➡️⚪
And here's the astonishing part:
A white dwarf can contain roughly the Sun's mass inside a sphere about the size of Earth. 🌍
It no longer produces energy through nuclear fusion. Instead, it slowly radiates away its stored heat and cools over billions of years.
