So, you think you know stuff about space, the night sky, astrophysics? Prove it. I'm warning you in advance, this is going to be tough. Tough, but fair. If you've got a degree in astronomy, or are a serious backyard/armchair astronomer, you should be able to get most of the questions.
To stop people from guessing, I give 4 points for a right answer, and 2 points for the "I don't know" option, which is the last option for each question. There are 25 questions, so a perfect score is 100 and answering "I don't know" every time will get you 50, while guessing randomly will average you about 33. So don't guess!
