This photo was taken in 2007 in Aso, Japan. The sun is 150,000,000 kilometers, or 93,206,000 miles from Earth. The sun was formed about 4.6 billion years ago when a hydrogen molecular cloud collapsed. The Sun does not have enough mass to explode as a supernova. Instead, in about 5 billion years, it will enter a red giant phase, its outer layers expanding as the hydrogen fuel in the core is consumed and the core contracts and heats up. We will all die. Fortunately, if you're reading this, you have no real chance of being alive in 5 billion years. But, still sad.
