Will the Stars Keep Shining Forever?
Scientists believe that our sun will go on shining in much the same way it does now for about 35 billion years more. Then the amount of light and heat it shoots our will get less and less, as it finishes burning up its fuel. Even so, it will probably keep shining with lessening brilliance for another 100 billion years or so.
Our sun is a rather slow atomic furnace. Other stats seem to be using up their hydrogen fuel much more rapidly. Most of the really brilliant stars pour out energy about 5,000 times faster than our sun does. These stars seem to be burning up faster, too and they probably quit shining billions of years before our sun dies out.

How Stars are used to Tell Directions.
The stars have always been used as guiding beacons in the sky. Since earliest times the North Star has helped sailors find their way across the trackless seas. Desert travelers have used stars to guide them. The Bible tells the beautiful story of the Star of Bethlehem that guided the Wise Men to the stable in Bethlehem where the baby Jesus lay in a manger. Even today, we use the stars to help guide our ships and airplanes.
How the Stars are used with Atomic Energy.
The study of the stars, including our sun, taught men the basic facts about how to make the powerful hydrogen bomb. Astronomers wondered how the stars could continue to shoot out such a tremendous amount of light and heat and not burn up in just a few years. They found that the stars seem to change atoms of hydrogen into atoms of helium. In the process some of the atomic material is changed into the energy of light and heat.
The stars have been put to other important uses as well. The value of star study cannot be measured only in terms of practical uses. Today as always, man marvels at the skies above and dreams for a better understanding of the universe. A good way to study the stars is to learn how to recognize the main constellations and read about how astronomers have learned what they know.
Movement of the Stars.
It is the motion of air that makes the stars seem to twinkle and it is the motion of the earth that makes the stars seem to rise in the east, move across the heavens and set in the west. This seeming daily motion of the stars is the result of the earth’s spinning around on its axis.
What seems to be another motion of the stars is also the result of the earth’s movements. You may have noticed that different star groups or constellations appear overhead at different seasons of the year. This is because the earth is rushing along in a great circle around the sun. So, at one time of the year, we look out at nighttime on one part of the heavens. Six months later, our earth has moved to the other side of the sun. Then we look out at nighttime on the other part of the heavens.
The stars, themselves, do move. Even our sun is rushing through space at a speed of about 43,000 miles an hour. We cannot see it go, however, because our earth and all the other planets are being carried right along with it.
All the stars in the universe seem to be rushing through space. And they all seem to be rushing away from each other, much as if they were dots of paint on a balloon that was being blown up. The farther away they are, the faster they seem to be moving.
