Roger Beazer, age 8, of Kingston, Ont., Canada, for his question:

WHERE DOES THE SUN GO AT NIGHT?

We might say that the sun sinks down in the western sky and goes to bed. The real truth is that the sun does not go anywhere at all. The whole thing just seems to happen because our world is a big ball that spins around like a dizzy top.

We live on one side of the big globe. The huge, beaming sun is miles out there in space. So are the stars and moon. As the earth spins around, it turns us to face first one view and then another of outer space. During the day, we turn to face the sun. At night we are turned away from the sun to face the opposite direction. When this happens, the far side of the globe faces the sun.
