So, have you ever wondered why some stars are brighter than others? You might think it's because they're closer to us, but that's not the whole story? In this episode of Crash Course Kids, Sabrina chats about how stars glow and how astronomers judge their brightness. Also, she talks about a really, really, really big star. This first series is based on 5th grade science. We're super excited and hope you enjoy Crash Course Kids! Venus Image Credit: Brocken Inaglory https://en.wikipedia.org/wi
