Outer Space Trace

Little boy in his childhood was very interested in the stars and wanted to learn all the constellations that then when he grows up to become a teacher of astronomy and talk about the stars the same as he did. But now he is still quite small and quite knows nothing of heavenly bodies and therefore requests your help to tell you all. Only if you really going to tell you do not do it for long because soon the day will come and you do not finish your story.
