Have you ever wondered what the sky
really is Long ago many thought it circled the earth, carrying the sun, moon,
planets, and stars with it. Since then scientists have found that it is really
just space. In this space the earth, moon, planets, sun, and other stars are
traveling. At times the sky changes its color. When the sun rises or sets, red, orange, yellow, or pink colors are seen. During a clear day the sky is very blue, and on a rainy day it is gray. At night it seems almost black except for the light from the moon and stars. People of old times thought the stars made pictures in the night sky. They saw bears, lions, and many other things. Sailors at sea and shepherds in fields with their sheep knew these. They need only to look. They can go out and view the night sky. No one knows how many stars are there in the sky.
