I'm by no means what you would call Space-savy, but I've always been interested in it. Tonight, I witnessed a star twinkling and shining many different colors like I had never seen one ever do before. Now, because I don't even remotely know what I'm talking about, I can only tell you that the star was in the Northeast sky. It was a bright star, and was twinkling very fast and many different colors. I'm wondering why a star would look like that, if the star itself is doing something, or if its the atmosphere causing its coloration.
