The North Star, also known as Polaris, has been a huge part of human culture, navigation, and a signature part of the sky. It’s so special because it is aligned with Earth’s axis, meaning that it will always point north! But, recently, scientists have imaged the surface of Polaris, revealing many interesting things about this star! What have these scientists discovered and how are they able to do this? In this episode, I will be speaking with Dr. Gail Schaefer. Dr. Schaefer is the director of GSU’s CHARA Array at Mount Wilson Observatory in California.
