Revised 18 September
Telescopes are instruments which use multiple lenses to produce magnified images of distant objects. It is unclear who invented the first telescope: lenses had been widely used in Europe to correct poor eyesight since the fourteenth century and I expect that, over time, the telescope was actually invented many times by different individuals, who discovered that combining different lenses could produce a magnified image.
In a spectacle maker called Hans Lippershey applied to the Dutch government for a patent for a device for seeing at a distance. His application was refused and, in the resulting publicity, the Italian astronomer Galileo Galilei () became aware of the device. Galileo refined the early telescopes to produce instruments with better magnification and in he took the first recorded astronomical observations with a telescope. Indeed, the first use of the word telescope, which is constructed from the Greek words &#;tele&#; meaning &#;far&#; and &#;skopos&#; meaning &#;seeing&#;, is associated with Galileo&#;s instrument.

Galileo Galilei Telescope Design
The history of telescope would not be the same if there was no Galileo Galilei (born on 15 February , died on 8 January at the age of 77), one of the most famous and influential Italian scientists from the age Renaissance. His involvement in telescopes, lenses and astronomy provided invaluable advancement of modern science, giving countless of other inventors, scientists, mathematicians and physicist new goals to reach and new possibilities of exploring their averment. He advanced engineering, built thermometer, calculated movement of celestial bodies, discovered phases of Venus, 4 moons of Jupiter, recorded topology of the moon, and many other achievements that helped his fellow scientists to immediately put those findings in effect. Just few decades after Galileo’s death, Isaac Newton published his Laws of Motion and Universal Law of Gravitation, which heavily leaned on the findings of Galileo Galilei and Johannes Kepler.
The first telescope Galileo Galilei ever built was made in , just one year after Dutch spectacle-maker Hans Lippershey tried to patent his simple telescope design. As the word of his invention spread across the Europe, se
How Galileo’s Telescope Created the Modern Science of Astronomy
Galileo challenged conventional views of the universe by observing by observing objects in the sky then applying the laws of mathematics and logic to what he saw. He turned the telescope into an important tool of understanding the universe we live in.
Before Galileo turned his telescope toward the night sky the act of astronomy was pretty much an astrological pursuit where objects and motions of object in the sky were explained using ancient and archaic understandings of the universe and how it works.
But he didn’t just observe and note new objects in the sky. He applied scientific methods, mathematical laws, and logical thinking to what he observed and it is this cross discipline approach that created the modern science of observational astronomy.
Galileo is often thought of as inventing the telescope. He didn’t invent the telescope but he was the first person to turn one toward the night sky. And the observations he made created the new science of modern astronomy where telescopes are used to help us understand our universe, our place in it, and how it works.

The Telescope
The telescope was one of the central instruments of what has been called the Scientific Revolution of the seventeenth century. It revealed hitherto unsuspected phenomena in the heavens and had a profound influence on the controversy between followers of the traditional geocentric astronomy and cosmology and those who favored the heliocentric system of Copernicus. It was the first extension of one of man's senses, and demonstrated that ordinary observers could see things that the great Aristotle had not dreamed of. It therefore helped shift authority in the observation of nature from men to instruments. In short, it was the prototype of modern scientific instruments. But the telescope was not the invention of scientists; rather, it was the product of craftsmen. For that reason, much of its origin is inaccessible to us since craftsmen were by and large illiterate and therefore historically often invisible.
Although the magnifying and diminishing properties of convex and concave transparent objects was known in Antiquity, lenses as we know them were introduced in the Wes
