The discoveries and inventions of the Italian astronomer. Galileo pioneered the use of the telescope for observing the night sky

Galileo was born in Pisa, Italy on 15 February 1564 (Julian calendar; 26 February 1564 by our modern day Gregorian calendar), the first of six children.. Prior to Galileo’s conflict with the Church, the majority of educated people in the Christian world subscribed either to the Aristotelian geocentric view that the earth was the center of the universe and that all heavenly bodies revolved around the Earth, or the Tychonic system that blended geocentrism with heliocentrism.

Galileo, though not the first inventor of the refracting telescope, significantly enhanced its power. In 1609, he learned of the spyglass and began to experiment with telescope-making, grinding and polishing his own lenses

Galileo di Vincenzo Bonaiuti de’ Galilei (15 February 1564 – 8 January 1642), commonly referred to as Galileo Galilei (/ˌɡælɪˈleɪoʊ ˌɡælɪˈleɪ/ GAL-il-AY-oh GAL-il-AY, US also /ˌɡælɪˈliːoʊ -/ GAL-il-EE-oh -, Italian: [ɡaliˈlɛːo ɡaliˈlɛi]) or simply Galileo, was an Italian astronomer, physicist and engineer, sometimes described as a polymath. He was born in the city of Pisa, then part of the Duchy of Florence.[4] Galileo has been called the father of observational astronomy,[5] modern-era classical physics,[6] the scientific method,[7] and modern science.[8]

He invented the thermoscope and various military compasses, and used the telescope for scientific observations of celestial objects. His contributions to observational astronomy include telescopic confirmation of the phases of Venus, observation of the four largest satellites of Jupiter, observation of Saturn’s rings, and analysis of lunar craters and sunspots.

The matter was investigated by the Roman Inquisition in 1615, which concluded that heliocentrism was foolish, absurd, and heretical since it contradicted Holy Scripture.[9][10][11]. Galileo later defended his views in Dialogue Concerning the Two Chief World Systems (1632), which appeared to attack Pope Urban VIII and thus alienated both the Pope and the Jesuits, who had both supported Galileo up until this point.[9] He was tried by the Inquisition, found “vehemently suspect of heresy”, and forced to recant

Copernicus is often described as a lone astronomer who defiantly argued that the sun, not the Earth was at the center of the cosmos. Copernicus’ contributions to astronomy are so significant that they warrant their own term: The Copernican Revolution.

First, as much as Copernicius’ ideas broke with the past, his model of the cosmos has more in common with his contemporaries than it does with modern day astronomy and physics. Second, although Copernicus’ sun centered model was revolutionary it was part of a series of early modern and renaissance innovations

Similarly, Johannes Kepler developed mathematical models for elliptical orbits that challenged some of the core assumptions of Aristotelian cosmology.. Looking back on these advances, exactly whose revolution was it? Or, given that each of these astronomers worked in ongoing traditions of modeling and understanding the heavens, was there a revolution at all?

Astronomy Today, 9e (Chaisson/McMillan) Chapter 2 The Copernican Revolution: The Birth of Modern Science. It was the Chinese who provided critical ancient data on supernovae and comets

When a planet retrogrades, it appears to move westward for weeks at a time. Like the Sun and the Moon, the planets appear to move from west to east from one day to the next

As originally stated, the Copernican model did no better job of predicting planetary behavior than did the Ptolemaic one. Galileo’s observations of the entire phase cycle of Venus proved that Ptolemy’s epicycles could not be correct in keeping Venus between us and the Sun

Throughout human history, astronomers have helped people understand what they see in the night sky. These famous astronomers — many of them great scientists who mastered many fields — explained space phenomena with varying degrees of accuracy.

On this list are some of the most famous scientists from the early days of astronomy through the modern era, and a summary of some of their achievements.. When most people believed the world was flat, the notable Greek mathematician, astronomer and geographer Eratosthenes (276–195 B.C.) used the sun to measure the size of the round Earth, according to NASA.

In ancient Greece, astronomer and mathematician Claudius Ptolemy (A.D. 90–168) set up a model of the solar system in which the sun, stars, and other planets revolved around Earth

Today, Galileo Galilei is synonymous with astronomy, scientific martyrdom and the telescope. Galileo was born on 15 February 1564 in Pisa, Tuscanyinto a changing world, one in which the Catholic Church was slowly losing power to Protestantism.

But astronomy was not his first love: Galileo was initially taught music, almost became a priest, studied medicine and was eventually appointed a professor of mathematics. It wasn’t until he was 40 that he started studying the night sky.

In the early 17th century, while teaching at the University of Padua, he invented the military compass. This, in a roundabout way, led him to take an interest in another military invention in 1608, one newly arrived from Holland: the telescope.

Galileo Galilei (1564-1642) is considered the father of modern science and made major contributions to the fields of physics, astronomy, cosmology, mathematics and philosophy. Galileo invented an improved telescope that let him observe and describe the moons of Jupiter, the rings of Saturn, the phases of Venus, sunspots and the rugged lunar surface

Galileo’s advocacy of a heliocentric universe brought him before religious authorities in 1616 and again in 1633, when he was forced to recant and placed under house arrest for the rest of his life.. Galileo Galilei was born in Pisa in 1564, the first of six children of Vincenzo Galilei, a musician and scholar

In 1583 he made his first important discovery, describing the rules that govern the motion of pendulums.. From 1589 to 1610, Galileo was chair of mathematics at the universities of Pisa and then Padua
