North Star's Surface Revealed for the First Time!

What does the surface of the North Star look like? Scientists recently imaged the surface of our North Star, Polaris, making it one of the very few stars whose surface details we’ve seen! We also have surface images of our Sun, the giant red star Betelgeuse, and the giant red star R Doradus. The image of Polaris is unique because its surface is blotchy, with light patches and dark patches. This could be because Polaris is a variable star, meaning it is known to change its brightness.
