September 2014: Twinkle, Twinkle, Variable Star

Despite the tumultuous and extreme conditions within our sun, its energy output varies only slightly - about 0.1%. Take a look at a red giant, though, and you could witness variabilities thousands of times that over the course of a single year. A great example of this is the first pulsating variable star ever discovered - Mira. Why does Mira behave this way, and what does it tell us about the fate of our own sun? Find out in this month's column!
