If one day, or rather a night, trying to count the stars will seem are many and that is impossible, but the truth is that you only need to count a long time and a good view. In the world there is a group of people already have, have had the stars in the sky. These people are able to spend whole nights watching the stars and best of all, I paid for it. They are astronomers and watch the sky is your job.
from observatories on top of a mountain or in the offices of universities, astronomers use complicated equipment for counting, measuring, photographing and studying the stars, doing everything possible to understand how the universe works.
Before it did not, in antiquity, astronomers had only their eyes to study the sky. Without any help to look could not see much detail. So instead of watching were the stars and planets, some rather imagined. This was a problem because their ideas were not always correct.
Everything changed one night in spring of 1609, exactly 400 years ago, when an Italian named Galileo Galilei decided to target a device called a "telescope" into the sky. Galileo invented the telescope, but it was the first person to use it for science, building on its ability to bring distant objects. Studied carefully how it works and managed to build an instrument higher powers.
Watching the sky with his telescope, Galileo saw that things were not like the other astronomers had expected. Found that the moon is not a smooth sphere, but I had mountains and valleys like the Earth. He also discovered that Jupiter had 4 moons, so the Earth was not the only one with a satellite spinning around. Studying the planet Venus was realized as the moon phases (new, waxing, full and waning) which was only possible if the earth revolved around the sun.
Since then there were no cameras, Galileo carefully drew everything he saw. Galileo was very important that all people knew what he had found, so I gathered together all his drawings and published a book that explained all these things he had seen. The book showed that the astronomers of the time were wrong and as nobody likes to be told he did a bad job, Galileo had to endure lots of criticism for the rest of his life.
2009 has been declared "International Year of Astronomy" to remember that night when Galileo Galilei changed the way you see the stars. Throughout this year, astronomers around the world to party and you're invited. If you love astronomy and have questions about stars, planets and universe now is when you meet them. Look out the page http://www.astronomia2009.org.mx and see the entire universe of conferences, workshops and observation nights Mexican astronomers have prepared for you.
At these events you will learn, among other things that a normal night, you can have a total of 100 000 stars, they are just the number of stars which, by its brightness, the human eye can see with the naked eye.
