The sun. It gives us life, it gives us essential vitamins that we need to survive, and it even helps us generate clean energy. Even though it is the only thing that allowed life develop on Earth, and the only thing that keeps us alive to this day, most people don't think much about the sun beyond the fact that it looks like a big yellow ball hanging in the sky.
But this video -- taken by NASA and shared online -- lets us get up close and personal with the blazing ball of energy that's so essential to our survival.
It's amazing how something can look so beautiful and so terrifying at the same time. I hope that this video taught you to appreciate our sun a bit more. I know it certainly had that effect on me.
