Detailed explanation-1: -After spending about 1 billion years as a red giant, our own sun will become a white dwarf, packing most of its initial mass into a sphere roughly the size of Earth. This fate awaits many other stars as well-all of them that are less than about eight times more massive than the sun, in fact.
Detailed explanation-2: -JOSHUA: Right, so the sun is about four and a half billion years old, and in about five billion years, it’s going to start to run out of its fuel. And then it will expand into what’s known as a red giant. So it’s going to expand to about a hundred times its size.
Detailed explanation-3: -But the white dwarf remains hot for some time, much like a stove burner still emits heat even when it has been turned off. After an extremely long time, all of the leftover heat will have radiated away. No longer emitting heat or light, the white dwarf will become a black dwarf.
Detailed explanation-4: -This white dwarf star will remain hot for an extremely long time. Heat is an amount of energy that gets trapped inside any object, but can only be radiated away through its surface. Imagine taking half the energy in a star like our Sun, then compressing that energy down into an even smaller volume.
