For centuries, travelers have referred to the Polaris, the North Star, as being a constant beacon to rely on. Recent research has found that the star is actually changing and has gotten brighter in the last few years. Scott Engle of Villanova University in Pennsylvania says the star is not a Standard Candle class object whose known brightness can be used to measure distances in space. Instead, scientists discovered about 100 years ago that Polaris is a Cepheid variable pulsating object. Looking back in history, Engle says the star appears to be more than four times brighter than it was in ancient times. Even though it went through a dimmer period about 20 years ago, Polaris is currently growing brighter. Engle says Cepheids like Polaris have been prized because even though they do pulsate, they remain fairly consistent. He added, ”It is possible that a good bit of Cepheids are undergoing these changes. They might be very, very complex stars, much more than we originally thought.”—Jim L. Wilson and Jim Sandell
