That excites the amateur astronomer in you because that must be the logical next step in the growth of your hobby. But how to buy a good telescope can be downright confusing and intimidating. Before you go to that big expense, it might be a better next step from the naked eye to invest in a good set of binoculars. But I bet you can remember as a child that very first time you saw the fully displayed clear night sky with all the amazing constellations, meters and comets moving about and an exposure of dots of light far to numerous to ever count. The best way to recapture the wonder of that moment is to go out in the country with a child of your own or one who has never had this experience and be there at that moment when they gaze up and say that very powerful word that is the only one that can summarize the feelings they are having viewing that magnificent sky. How to Look Up The beauty of astronomy is that anybody can do it. From the tiniest baby to the most advanced astrophysicist, there is something for anyone who wants to enjoy astronomy. In fact, it is a science that is so accessible that virtually anybody can do it virtually anywhere they are. All they have to know how to do is to look up. This theory has some credibility and, if it is true, it evokes some pretty startling images and foreboding fears in the current reining species on earth, the human race. The fact that asteroids are fast moving space debris only makes their movement and activity more interesting and exciting. Unlike a moon, planet or star, the odds that an asteroid could hit the earth are entirely reasonable and in fact, there are many documented cases of small asteroids making it through our atmosphere and leaving some pretty impressive craters in the earth s surface. Maybe it s all the science fiction stories about visiting the moon, Mars and other planets. But we love to think about those planets that make up what we call the solar system. that do what our planet does but do it very differently indeed. The planets of our solar system have taken on personalities and mythical appeal in our literature and arts. Scientists refer to a comet that is expected to burn out or impact the sun within two hundred years as a short period comet whereas a long period comet has a life expectancy of over two hundred years. That may seem long to us as earth dwellers but in terms of stars and planets, this is a very short life as a space object indeed.
