What If the Sun Exploded Tomorrow?

Correction: we mixed up the Sun’s lifespan with its age. Of course, the sun is only about 4.6 billion years old, halfway through its lifespan of about 10 billion years.

That star at the center of our Solar System, that super hot ball of plasma that gives us heat and energy, and amazing complexions...well, it's a ticking time bomb. The Sun is about 10 billion years old. But it's only expected to last about another 5 billion years. After that, the Sun will expand, becoming a red giant. Then it will shrink to become a white dwarf, a dying star, cooling for the next several billion years. Of course, we'll all be long gone before any of that happens. But still, can you imagine what it would be like to watch the Sun blow up before your very eyes?
