Jenny and Brian go to visit Danny. When they arrive, Danny is outside in the yard. Brian：Hi Danny. What do you have there Danny：It’s a telescope. I told my father that we were studying the solar system. He said that I could use his telescope. (He looks through the telescope.) That’s funny! I can see only a tiny circle of light. Jenny：(She laughs.) You’re looking through the wrong end, Danny! Try looking through the other end. (Danny turns the telescope around and looks through it again. ) Danny：That’s better! But I still can’t see any stars or planets. Brian：You certainly can’t, Danny! The sun is shining. The stars come out at night. Jenny：The sunset today is around 7: 00 p. m. Maybe Brian and I can join you after supper. I would love to look through your telescope. Danny：Great. You two can help me. Brian：Help you What are you trying to do Danny：I want to discover a new planet. Brian：I don’t think you can find one unless you have a bigger telescope. Scientists use huge telescopes when they look for planets. Danny：Bigger than mine Jenny：Bigger than your whole house! Actually, double the size of your house! Danny：Well, it’s worth a try, even if I don't find a planet. Brian：We can try tonight. The universe is a mystery. Maybe we’ll find other amazing things!
