Introduction to Astronomy: Crash Course Astronomy #1
Comets - Visitors From Beyond The one thing we love the most in the world of astronomy is a good mystery. And if there was ever a mysterious and yet very powerful force of nature that we witness in the night skies, it is the coming of the mighty comet. We should never confuse comets with asteroids. Asteroids are small space rocks that come from an asteroid belt between Mars and Jupiter.
It almost makes you think that we should put more energy and money into the space program, not less because it seems to be a bond that heals tension rather than creates it. Why is astronomy so exciting even though we have no dinosaurs, moving animals or any real danger to most who are obsessed with the discipline?
To us, it is the one and only moon. The moon works its way into our way of thinking, our feelings about romance, our poetry and literature and even how we feel about our day in day out lives in many cases. It is not only primitive societies that ascribe mood swings, changes in social conduct and changes in weather to the moon.
But the solar system is not just made up of these planets. The solar system is a very busy place indeed. In 2006, there was quite a bit of controversy as scholars and astronomers agreed to downgrade Pluto and remove its status as a planet. So you have to wonder, what is it that makes something a planet and what happened to Pluto?
But it pretty cool once you find it. These are the obvious starting places but from The Little Dipper you can find the constellation known as The Swan or Cygnus. Just use the same system you used to find The North Star but continue drawing that line that started in those pointer stars in the bowl of The Big Dipper.
But then we have the coming of Einstein and the theory of relativity to set the entire idea on its ear. All of a sudden space is not just three dimensions but the dimension of time becomes exportable and the twisting and maybe even travel through time seems almost possible. The frontier of space is as much a journey of the mind as it is of distance.
