Who invented the astronomical telescope and what was the world s first astronomical telescope

Galileo telescope. Italian astronomer and physicist Galileo Galilei invented the first astronomical telescope in human history in 1609.

It's called the Galilean telescope. The Galilean telescope means that the objective lens is a convex lens.

converging lenses) while eyepieces are concave lenses (divergent lenses.

of telescopes. The earliest telescopes were refracting monoculars, said to have been created in the 17th century (around 1570) by Lippershey, an eye keeper in a small Dutch town.

One day, in order to review the quality of the polished lenses, he put a convex lens and a concave lens.

Lined up in a line and looking through the lens, he invented the distant church spire as if it had been pulled closer and enlarged, so he inadvertently invented the secret of the telescope.

In 1609, when Galileo learned about it, he reformed the optician's telescope with his profound knowledge of physics, and made a telescope with a magnification of 32 times. Galileo turned his lens to the moon for the first time.

This is the first scientific observation of the lunar surface.

A telescope is an optical instrument that uses concave and convex lenses to observe distant objects. The light refracted through the lens or the light reflected by the concave mirror makes it enter the small hole and converge for imaging, and then it is seen through a magnifying eyepiece, also known as a "clairvoyant".

The Galilean telescope has a convex lens, a concave lens, in the middle of which there is a real image, and reticles can be placed on the real image surface, the Galilean telescope.

The focus is behind the eyepiece.

The astronomical telescope was invented by Galileo. In historical records, no one before him had equipped an unformed telescope with a stable stand for systematic astronomical observations, and these two are the most important features of astronomical telescopes.

Galileo was the first scientist to use a telescope to observe celestial bodies and achieve a large number of results. In 1609, after Galileo learned that the Dutch already had a telescope, Galileo created an astronomical telescope (later known as the Galilean telescope), which was used to observe celestial bodies and discover many previously unknown astronomical phenomena. He found that the number of stars seen increased with the magnification of the telescope; The Milky Way is made up of countless individual stars; Moon.

There are bumps in the surface (the first map of the moon was drawn by hand), the waxing and waning of Venus; Jupiter.

There are four moons (in fact, the four largest of the many Europa, now known as the Galilean moons). He also discovered sunspots and believed that sunspots were a phenomenon on the surface of the sun. From the rotation period of the sunspot on the surface of the sun, he concluded that the rotation period of the sun is 28 days (actually days).

In 1637, when his eyesight was very poor, he also discovered the moon's circumferential loss and the balance of the moon and the moon. These discoveries ushered in a new era in astronomy. Galileo was the first to observe Saturn's rings, sunspots, lunar ridges, Venus, and Mercury with a telescope.

The phenomenon of profit and loss, the moons of Jupiter and the circumferential phase of Venus, and the law of free fall and the law of inertia are summarized from the experiment.

and Galileo's principle of relativity, etc. Thus overturning many assumptions of Aristotelian physics, laying the foundations of classical mechanics and refuting Ptolemy.

The geocentric system strongly supported Copernicus.

The heliocentric doctrine.

In 1608, Hans Lippolsay, an unknown optician in Middelburg, the Netherlands, built the world's first telescope.

The original idea was not Galileo, he was inspired to make and improve it, but based on his contributions, everyone considered him to be the inventor.

One day at the beginning of the 17th century, Kobisch, the owner of an optical shop in the town of Mittelsburg in the Netherlands, in order to check the quality of the polished lens, arranged a convex lens and a concave mirror in a line, looked through the lens, and found that the tower of the church in the distance seemed to be getting bigger and closer, so he accidentally discovered the principle of the telescope. In 1608 he patented a telescope he had made, and at the behest of the authorities, he built a Kejan binocular. It is said that dozens of opticians in the town of Mitttelburg claimed to have invented the telescope, although it is generally believed that Liebich was the inventor of the telescope.

Hope it can help you, please give a "good review".

The astronomical telescope was invented by Galileo.

In 1608, an apprentice of the Dutch spectacle maker Hans Ripach stumbled upon the idea that stacking two lenses on top of each other made it possible to see things in the distance clearly. In 1609, when the Italian scientist Galileo Galilei heard about this invention, he immediately built his own telescope and used it to observe the starry sky. Since then, the first astronomical telescope has been born.

Galileo Galilei was an Italian astronomer, physicist and engineer, and the founder of modern natural science in Europe. Galileo is known as the "Father of Observational Astronomy", "The Father of Modern Physics", "The Father of the Scientific Method", and "The Father of Modern Science".

Galileo used his telescope to observe sunspots, lunar craters, Jupiter's moons (Galileo's moons), and the waxing and waning of Venus, which strongly supported Copernicus's heliocentric theory. Galileo's telescope was made using the principle of refraction of light, so it was called a refractor.

Since Galileo Galilei built the first telescope in 1609, telescopes have continued to develop, from optical bands to full bands, from the ground to space, telescopes have become more and more observant and can capture more and more celestial information. At present, human beings are expected to have telescopes in the electromagnetic band, neutrinos, gravitational waves, cosmic rays, etc.

Galileo's main contributions:

1. Mechanics. Galileo Galilei was the first scientist to introduce experiments into mechanics, and he used a combination of experiments and mathematics to determine some important laws of mechanics.

2. Astronomy.

He was the first scientist to use a telescope to observe celestial bodies and achieve a large number of results. These achievements include the discovery of the uneven surface of the Moon, the four moons of Jupiter (now known as the Galileo moon), the black and wide dates of the Sun and the rotation of the Sun, the waxing and waning of Venus and Jupiter, and the innumerable stars of the Milky Way.

He used experiments to confirm Copernicus's "theory of earthly motion" and completely refuted the "theory of earthly motion" of Aristotle and Ptolemy, who ruled for more than a thousand years.

3. Philosophy. Throughout his life, he persisted in the struggle against idealism and the scholasticism of the Church, advocating the use of concrete experiments to understand the laws of nature, believing that experiments were the source of theoretical knowledge. He did not admit that there is absolute truth in the world and the absolute authority to grasp the truth, opposed blind superstition, and he recognized the objectivity and diversity of matter and the infinite nature of the universe, and these views were of great significance for the development of materialist philosophy.

4. Thermal. The first thermometer was invented in 1593 by the Italian scientist Galileo Galilei (1564-1642).

5. The principle of relativity.

On the basis of the discovery of the law of inertia, Galileo proposed the principle of relativity: the laws of mechanics are equivalent in all inertial coordinate systems. The mechanical process is exactly the same for the stationary inertial frame and the moving inertial frame.

The first astronomical telescope was invented by Galileo.

In 1609, Galileo made a telescope with a caliber of centimeters and a length of about meters. He used a plano-convex lens as the objective lens and a concave lens as the eyepiece, and this cavernous optical system is called a Galilean telescope. Galileo Galilei pointed the telescope to the sky and made a series of important discoveries, and astronomy entered the telescope age.

Galileo's work was groundbreaking, he was the first person to point a telescope at the sky, and the appearance of the telescope greatly broadened the horizon of human observation of space, opened a new era of astronomy, and opened the door to modern astronomy. The prevailing saying at the time was: "Columbus discovered the New World, Galileo discovered the New Universe".

In 2009, the United Nations designated the International Year of Astronomy to commemorate the 400th anniversary of Galileo's first astronomical observations with a telescope.

Galileo's contributions

Galileo Galilei was the first scientist to introduce experiments to Linawa, and he used a combination of experiments and mathematics to determine some important laws of mechanics. Around 1582, after a long period of experimental observation and mathematical calculations, he obtained the law of isochronism of the pendulum, and then dropped out of school in 1585 due to financial difficulties due to his family's hunger.

While away from the University of Pisa, he delved into the writings of ancient Greek scholars such as Euclid, Archimedes, and others. Based on the principle of levers and buoyancy, he wrote the first article entitled "The Balance". Soon after, he wrote ** "On Gravity", which revealed the essence of gravity and the center of gravity for the first time and gave accurate mathematical expressions, so it became famous.

At the same time, he questioned many of Aristotle's views.

The first astronomical telescope was invented by Kepler.

Kepler invented a convex lens telescope in 1608 that could magnify 3 times. In 1609, he invented an astronomical telescope with 9x magnification to observe celestial bodies. Kepler's telescope is made up of two convex lenses.

By varying the distance between the two lenses, the magnification of the telescope can be adjusted.

The advantage of this type of astronomical telescope is that it can observe clearer images and can observe celestial objects farther away. Kepler's astronomical telescopes can be used to observe not only celestial bodies, but also objects on Earth. He used this telescope to observe the details of the surface of the moon with raised hands, proving that the moon is made up of mountains and plains.

The impact of astronomical telescopes on humanity

Astronomical telescopes have given mankind a deeper understanding of the universe. Through the observation of celestial bodies, we can learn more about the universe, such as the trajectory of stars, the evolution of galaxies, etc. This knowledge can not only satisfy human curiosity about the universe, but also create more technologies and applications for human beings.

Astronomical telescopes have brought about advances in science and technology. In the study of astronomy, people need to constantly improve and innovate telescope technology to obtain more accurate data and images. This has promoted the development of science and technology, and has also provided inspiration and support for technological progress in other fields.

Zhengbu. The invention of the astronomical telescope also promoted international cooperation and exchanges. Astronomy is an international science that requires the cooperation and joint efforts of scientists across the globe. By sharing data and research results, scientists from all over the world can study the universe more deeply, and international scientific exchanges and cooperation can also be strengthened.

Galileo. Galileo Galilei was an Italian mathematician, physicist, astronomer, and pioneer of the scientific revolution. Galileo Galilei invented the pendulum needle and thermometer, made great contributions to mankind in science, and was one of the founders of modern experimental science.

Historically, he was the first to integrate the knowledge of mathematics, physics and astronomy on the basis of scientific experiments to expand, deepen and change human understanding of the movement of matter and the universe. Galileo summarized the law of free fall, the law of inertia, and Galileo's principle of relativity from experiments. This overturned many assumptions of Aristotelian physics, laid the foundation of classical mechanics, refuted Ptolemy's geocentric system, and strongly supported Copernicus's heliocentric theory.

He overthrew the purely speculative traditional view of nature through systematic experiments and observations, and created a modern science based on experimental facts and a rigorous logical system. Therefore, he is known as the "father of modern mechanics" and "the father of modern science". His work laid the foundation for the establishment of Newton's theoretical system.

Galileo advocated a combination of mathematics and experimentation, which was the source of his great achievements in science and his most important contribution to modern science.

Galileo believed that experience was the only source of knowledge, and advocated the use of experimental-mathematical methods to study the laws of nature, opposing the mystical speculation of scholasticism. Convinced that the Book of Nature is written in the language of mathematics, and that only shape, size, and velocity, which can be reduced to quantitative characteristics, are objective properties of objects. He was the first person to use the telescope to observe celestial bodies and achieve a large number of results.
