How Astronomy Telescopes Work

In our world of universe exploration, several countries have their own variations of advanced technological models of shuttles and rocket ships to send up into space. Highly trained astronauts are sent up to explore the galaxy and to carry out numerous kinds of experiments. Humans have always had a unique curiosity of how the world works and that includes our galaxy too. Way before shuttles and rockets, there were astronomers like the infamously Galileo Copernicus.

Throughout several centuries, telescopes have continuously helped our astronomers discover many mysteries of the universe way before an astronaut and rocket were ever thought to be possible. By these curious and determined astronomers of the beginning in the official study of the stars, astrological records have been kept for many centuries with surprising accuracy and miraculous understandings of the universe with only the blind eye, meticulous record keeping and eventually, the wonderful invention of telescopes. Telescopes have always brought to the astronomers mounds of information and valuable knowledge of outer space without ever having to be an astronaut shooting up into the galaxy.

When it comes to telescopes, it is like the adage of \'bigger is better\', because the larger the telescope, the more magnified significant smaller objects are. Expansion of distance will also be brought to our knowledge with a telescope further the than the naked eye will go. There are vasts amount of layers with the aspects, dimensions and knowledge that can be studied of the ever magnificent astrological space above us.

Many telescopes are of high quality, and can be built with some slight technical differences between them, but they still do the same job in our study of the stars. Some of the most common telescopes to purchase for using at home fall under three different model classifications. These three classifications are the reflector telescope, the refractor telescope and the compound telescope. These variations of telescopes are not of the biggest in size, but do an excellent job for those wanting a quality telescope for using at home.

The refractor telescope gathers the light at a certain focal point, while working with the magnifying lens, to give the naked eye a much closer view of very far away images in the night sky. The reflector telescopes are also known as catoptric telescopes and eliminates the appearance of \'rainbow-like halos\' that are sometimes known to occur with the refractor telescope. Sir Isaac Newton took a refractor telescope and added an extra mirror for \'reflecting\' all that the refractor telescope gathered. The compound telescope is also known as the catadioptric telescope, and is a combination telescope of both the refractor and the reflector telescopes.

When it comes to larger observatory types of telescopes, there are some telescope designs that use radio waves, gamma rays and x-rays. In the Arecibo Observatory for example, it is the radio telescopes that are used. The radio telescopes do not have mirrors, but uses dishes with holes instead. Gamma and x-ray telescopes are for use in outer space, because our atmospheric condition is not right for allowing these types of rays to properly work.

For studies by professional astronomers, there is one known observatory that utilized the method of x-rays and that is the Chandra X-Ray Observatory. The Spitzer Space Telescope is another famous telescope and does its detections with infrared radiation. No matter the types of telescopes used, they all are indispensable tools in the field of astronomy, and feed all of us with vast valuable amounts of information without ever leaving the earth.
