Why is NASA so important?

NASA or National Aeronautics and Space Administration is important to us because NASA gives us information about the earth and what we are doing to it that may effect our lives.

When Will The Sun Explode?

Don’t worry that won’t happen for at least another five hundred million years. Eventually (in five or seven billion years time), the Sun’s life will come to an end. Our star will swell up, becoming something called a “Red Giant” star. It might even get so big that it swallows the Earth whole. (From “The Conversation”)
