Beyond the Solar System

Number of pages: 35
Studying the distant suns that twinkle in the sky is, you will find, a great strain on the imagination. If you are to get a true picture of the stars, you will have to imagine temperatures so high that the temperature in the center of a furnace fire would be cool beside them. You will have to imagine distances so great that the distance from the earth o our sun seems only a step. You will have to imagine sizes so large that they make the earth seem a mere speck. You will have to imagine, too, periods of time so long that a hundred years seems to be no time at all.
