It is not only primitive societies that ascribe mood swings, changes in social conduct and changes in weather to the moon. Even today, a full moon can have a powerful effect on these forces which we acknowledge even if we cannot explain them scientifically. The most obvious physical phenomenon that is directly affected by the gravity of the moon are the tides of the ocean. Here are some steps you can take to make the moments you can devote to your hobby of astronomy much more enjoyable. -Get out of town. The furtherest you can get from the lights of the city, the more you will see in the night sky. -Know what you are looking at. It is great fun to start learning the constellations, how to navigate the night sky and find the planets and the famous stars. There is historical evidence that astronomy was a recognized science as far back as the Babylonian civilization hundreds of years before Christ. But the study of the stars was not limited to one country. There were similar movements going on in China, India, and Ancient Egypt and all over the Arabian Peninsula. A good star map will show you the major constellations, the location of the key stars we use to navigate the sky and the planets that will appear larger than stars. And if you add to that map some well done introductory materials into the hobby of astronomy, you are well on your way. The next thing we naturally want to get is a good telescope. But of the many celestial phenomenons, there is probably none as exciting as that time you see your first asteroid on the move in the heavens. To call asteroids the rock stars of astronomy is simultaneously a bad joke but an accurate depiction of how astronomy fans view them. Unlike suns, planets and moons, asteroids are on the move, ever changing and, if they appear in the night sky, exciting and dynamic. These little fun facts should get a pretty spirited discussion going about the origins of the universe and about the possibility of space travel or if there are life on other planets. You can challenge the kids to calculate that if every star in the Milky Way supported nine planets and if only one of them was habitable like earth is, what are the odds that life would exist on one of them?
