Brian:Hi Danny.What do you have there
Danny:It’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.
Careful reading
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!
The earth, the sun and the moon all belong to the solar system. Our solar system is in a galaxy called the Milky Way. The Milky Way has more than five hundred billion stars. Scientists say the universe contains billions of galaxies. Do you think there is life on other planets
