Tools of the Astronomer :: essays research papers

The Telescope of the Astronomer years and Years ago, astronomers didnt progress to the advantage of the telescope. They could only use their naked eye. It wasnt until Galileo first do a better telescope that it could be used for looking into space. most every telescope you buy today is better than the one he used. These telescopes have revolutionized astronomy in general.When Galileo first took his telescope and looked at the alternate he saw amazing things. He saw craters on the Moon, darkling spots on the surface of the Sun, tiny moons moving around Jupiter. No one else had ever seen these things. With the modern telescopes we use today, we tail assembly see galore(postnominal) umpteen more things.Light from planets, stars and galaxies spreads itself on Earth, and a telescope get togethers this write down and lets us look at the object the firing came from. Some telescopes, called refracting telescopes, collect and focus heat through a glass lens. Another type, the st rikeing telescopes, reflect light on a glass mirror. The bigger the telescope the more light it collects, giving us a better view of what we require to look at. Some dont have just one big mirror, it has many little mirrors that fit together like bathroom tile. With the help of a computer, these little mirrors work together like one big mirror. The Hubble pose Telescope is the largest orbiting optical telescope in history.The refracting and reflecting telescopes collect and focus indubitable light, which is light that we can see. There are also other types of light that we cannot see. Nowadays astronomers have telescopes to looks at different types of light. On Earth we can look at visible light and radio waves. A a couple of(prenominal) of the very largest telescopes look for radio light. Other types of light, like X-ray light and ultraviolet light, can only be looked at from space, so astronomers have built telescopes in space that orbit the Earth. The most famous is the Hubbe ll spot Telescope.
