QUESTION OF THE DAY:
Will the Sun blow up someday?
Yes, but it's best to keep your sunscreen handy for a few more years. The experts at NASA explain that the Sun, since it is a "red giant star," will one day become bigger, brighter, and cooler, but that day won't be for another 5.5 billion years. To put that in perspective, realize that the Sun is currently 4.5 billion years old. In the end, it will shed its outer envelope, which will become a "planetary nebula," or gaseous shell. The remnants of the Sun will be a hot, burned-out stellar core, which is fancy talk for a star that's about to die.
