Who invented the first telescope and how change the science of Astronomy?

Answer 1

Concave and convex lenses had been developed in the 15th and 16th centuries to correct near-sightedness and long-sightedness. The existence of these lenses made the fashioning of telescopes possible.

The practical implementation and manufacture of the instrument was certainly achieved in the Netherlands about 1608, but the credit of the original invention has been claimed on behalf of three individuals, Hans Lippershey and Zacharias Janssen, spectacle-makers in Middelburg, and Jacob Metius of Alkmaar also known as Jacob Adriaanszoon.

The original Dutch telescopes were composed of a convex and a concave lens, and telescopes so constructed do not invert the image. Telescopes seem to have been made in the Netherlands in considerable numbers soon after the date of their invention, and rapidly found their way all over Europe.

Galileo, happening to be in Venice in about the month of May 1609, heard that a Belgian had invented a perspective instrument by means of which distant objects appeared nearer and larger, and that he discovered its construction by considering the effects of refraction.

Galileo states that he solved the problem of the construction of a telescope the first night after his return to Padua from Venice, and made his first telescope the next day by fitting a convex lens in one extremity of a leaden tube and a concave lens in the other one.

A few days afterwards, having succeeded in making a better telescope than the first, he took it to Venice, where he communicated the details of his invention to the public, and presented the instrument itself to the doge Leonardo Donato, sitting in full council.

The senate, in return, settled him for life in his lectureship at Padua and doubled his salary. Galileo may thus claim to have invented the telescope independently, but not until he had heard that others had done so.

Galileo devoted his time to improving and perfecting the telescope, and soon succeeded in producing telescopes of greatly increased power. His first telescope magnified three diameters; but he soon made instruments which magnified eight diameters, and finally one that magnified thirty-three diameters.

With this last instrument he discovered in 1610 the satellites of Jupiter, and soon, afterwards the spots on the sun, the phases of Venus, and the hills and valleys on the Moon.

These brilliant achievements, together with the immense improvement of the instrument under the hands of Galileo, overshadowed in a great degree the credit due to the original inventor, and led to the universal adoption of the name of the Galilean telescope for the form of the instrument invented by Lippershey.

When Galileo pointed his x 33 telescope at Jupiter and discovered the four largest Jovian moons on 7th January 1610, it was the observational evidence needed to support the Copernican theory of a heliocentric Solar System: if four moons rotated around Jupiter then plainly everything did not revolve the earth, as the geocentric theory advanced by Ptolemy 1400 years previously had maintained.

Later that year Galileo used his telescope to study Venus and established it shows a full set of phases like the Moon does. This too supported the Copernican theory that the Sun was at the centre of the Solar System and the earth revolved around it,

This might sound grandiose but the Dark Ages were finally over, and the Scientific Revolution had begun and the telescope was the instrument that enabled the key breakthrough to occur.

The mid-twentieth century historian, Herbert Butterfield saw the change as fundamental and a decisive break with the past:

"Since that revolution overturned the authority in science not only of the middle ages but of the ancient world — since it ended not only in the eclipse of scholastic philosophy but in the destruction of Aristotelian physics — it outshines everything since the rise of Christianity and reduces the Renaissance and Reformation to the rank of mere episodes, mere internal displacements within the system of medieval Christendom.... It looms so large as the real origin both of the modern world and of the modern mentality that our customary periodization of European history has become an anachronism and an encumbrance."

Answer 2

The invention of the telescope was a major advance in the science of Astronomy, but who invented it? Maybe you think you already know the answer.

Well, what would you say if I told you that you're probably wrong? After all, it was Galileo Galilei who invented it, right? You might be surprised by the answer to that question. Although Galileo Galilei was a great astronomer, he didn't invent the telescope.

If not Galileo, then who?

A man named Hans Lipperhey invented the telescope. He was born in Wesel, Germany and made his home in Middleburg, part of the Zeeland province in the Netherlands. He was married there in 1594, and became a citizen in 1602. He was a spectacle-maker by trade.

The Italians developed new glass-making techniques which were introduced to the Netherlands in the 1590's. These new techniques helped to bring about new ideas and innovations in the glass-making community and people started to experiment with different ways to combine lenses.

Where is the proof?

Many other people claim to have invented the telescope, but Hans Lipperhey is the only person documented to have applied for a patent for the device.

Child's play

Legend has it that it wasn't Hans himself, but his children who actually invented the telescope while they were playing.

So now you know the story of the telescope and how it came to be.

Answer 3

telescopes were invented by Galileo

and i dont know what u mean by change of astronomy?
