The sun will spend most of its life steadily burning its vast reserves of hydrogen fuel, which will last for at least another five billion years. But eventually, the fuel will run out, and its core will collapse. Then, something remarkable will happen: the sun’s outer layers will expand, and its colour will shift. Mercury will be little more than a memory as it’s engulfed by the expanding red sun. –Brian Cox
