 So this is a really cool tool that astronomers, and I'm not an astronomer, but I love to share the night sky with people. So I don't know how they did it before this. You are light-sabering outer space. Isn't it cool? I wish that Rebecca had one too. I love this thing. What is this? What's it called? It's a laser pointer. No, but it's not a normal laser pointer. It is.
