It will continue to do so for another 4.

It is massive almost beyond comprehension.

Constant, yet ever changing.

Born from a swirling cloud of dust and gas, it is a giant fusion engine that drives the

solar system.

It seethes and boils like a living thing.

Loops of plasma rise up, so large they would dwarf Earth.

Explosions flash on its surface.

And yet the sun also gives us warmth. And life. And beauty.
