Your study of the moon, like anything else, can go from the simple to the very complex. To gaze at the moon with the naked eye, making yourself familiar with the lunar map will help you pick out the seas, craters and other geographic phenomenon that others have already mapped to make your study more enjoyable. And to be sure, that is the exciting area of astronomy that accounts for it s huge popularity. So to the uninitiated, the idea of radio astronomy seems strange. There are two reasons for that. First is that humans are far more visual than audio oriented. And the second is that radio astronomy doesn t really involve listening to the cosmos except to the extent that scientists who use this sophisticated form of stargazing do not rely on visual study to conduct their work. 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. On top of that, it is a thriving area of fascination and one of the most exciting hobby areas going with thousands of astronomy clubs and tens of thousands of amateur astronomers watching the stars every night just like we do. But did you know that astronomy is one of the oldest and most respected sciences of them all? At the time when you see the first one, it s easy to remember the movie war of the worlds or some other fantastic image of aliens entering our atmosphere in droves to take over the planet. But with some guidance and explanation of what was going on, we eventually learned that these showers were not at all threatening or any kind of invasion. In addition to the regular planets and moons, there are dwarf planets, asteroid belts and routine visits by comets that create a lot of traffic in our cosmic corner of the universe. The two known dwarf planets that exist on the outer rim of our solar system are Eries and Ceres. So when Pluto s status was changed to be removed from the list of planets, it simply joined those two bodies as dwarf planets but still a solid citizen of the community of celestial bodies around our sun.
