How did Galileo 's observation of Jupiter and Venus support Copernicus' model?

Galileo's discoveries with the telescope sowed doubts about the ancient Ptolemaic model which had the Earth at the centre. First, Jupiter's moons orbited round Jupiter and not the Earth, the first objects that had been discovered that were not orbiting the Earth. Secondly the discovery of the phases of Venus raised doubt about the Ptolemaic model, particularly the gibbous phase when, we now know, Venus is round behind the Sun as seen from Earth. In the Ptolemaic model Venus never goes behind
the Sun (as seen from Earth) and the gibbous phase cannot happen.
By implying in the title of his book 'Dialogue of the two world systems' that there were only two models in contention, those of Ptolemy and Copernicus, Galielo insinuated that if the Ptolemaic model was incorrect the Copernican system must be correct. This was logically flawed because at the time there were two other systems in the public domain that both explained Venus's phases. These were the models of Tycho, which was geocentric, and finally Kepler's which was heliocentric.
Of these four, Kepler's was eventually accepted by everyone after Newton's theoretical discoveries showed that Kepler's elliptical orbits for the planets agreed with the new theory of dynamics.

How did Galileo's observations of Jupiter's moons support Copernicus theory?
The discovery did not support Copernicus's theory directly but it raised doubts about the ancient theory of Ptolemy that said that all objects in the sky are in orbit round the Earth. Galileo was an aggressive supporter of Copernicus's theory but eventually it was Kepler's theory that became accepted and is still used today. Both Copernicus and Kepler placed the Sun at the centre but Kepler's elliptical orbits are supported by the later theory of dynamics.
How did galileo's observation support the heliocentric system?
Venus goes through phases similar to those of Earth's moon.#1Direction
How did Galileo observations support the idea of the heliocentric system?
Galileo's observations with his telescope supported the concept of heliocentricism. He noted that the satellites of Jupiter and Venus, based on their range of phases, did not match geocentricism supported by Ptolemy. He noted that based on these findings, that the Heliocentric theory was correct.
What model did Copernicus support?
He thought of and supported the heliocentric model, which states the "heavens" revolve around the Sun.
How did keplers work improve on or support Copernicus heliocentric theory?
Kepler completely replaced Copernicus's theory of the orbits of the planets, which was based on circles an epicycles, with a new theory using elliptical orbits. However Kepler retained Copernicus's idea of placing the Sun at the centre.

The scientist who first used a telescope to make discoveries that supported the heliocentric model was?
Galileo Galilei . He only helped support the theory through his observations , he didn't invent the model, Copernicus did.
What discoveries did Galileo make to support Copernicus' ideas?
Through his observation Galileo watched the motions of the planets and the sun. Using triginometry and geometry, he flat out knew that the earth could not be a stationary body. He also knew that the Earth could not be the center of the universe. The math told him otherwise. This was in direction contridiction of church doctrine and more in line with the helocentric theory that Copernicus came up with. Also the phases of Venus that he observed could only be possible if the Earth and other planets revolved around the Sun.He also discovered 4 of Jupiter's moons. This showed that there were objects revolving around other planets and not everything revolved around the earth
Galileo's observation of the phases of Venus supported Ptolemy's epicycles?
Galileo's telescopic observations of the 4 large moons of Jupiter and the phases of Venus helped support the heliocentric model of the solar system developed by Copernicus. Copernicus predicted that all phases would be visible since the orbit of Venus around the Sun would cause its illuminated hemisphere to face the Earth when it was on the opposite side of the Sun and to face away from the Earth when it was on the Earth-side of the Sun. In contrast, the geocentric model of Ptolemy predicted that only crescent and new phases would be seen since Venus was thought to remain between the Sun and Earth during its orbit around the Earth. Galileo's observations of the phases of Venus proved that it orbited the Sun and lent support to (but did not prove) the heliocentric model.

What other scientific breakthroughs did the work of Galileo Galilei lead to?
In the opinion of many historians, Galileo Galileo studies of the universe led to Sir Issac Newton's discoveries on the laws of gravity. Galileo's support of Copernicus and his idea that the earth revolved around the sun, led Galileo into prison as this idea went against Church theology. After Galileo recanted he was freed.
Who is Galileo from Jupiter?
Galileo can refer to a measurement unit, a song, a play, a film, a Japanese TV series, or to a NASA space probe that studied Jupiter between 1995 and 2003 . All but the TV show are based on the Italian astronomer and scientist Galileo Galilei (1564-1642).A unit of gravitational measurement, galileo or gal, is equal to 1 centimeter per second squared (1 cm/s2).Galileo GalileiGalileo, born in Tuscany, was a physicist, mathematician, astronomer, and philosopher who played a major role in the scientific revolution. His achievements include improvements to the telescope and consequent astronomical observations, and support for Copernicanism (the heliocentric solar system).His contributions to observational astronomy include the telescopic confirmation of the phases of Venus, the discovery of the four largest satellites of Jupiter, (named the Galilean moons in his honor), and the observation and analysis of sunspots.(see related question)
Is Galileo an astronomer?
Galileo Galilei, commonly known as Galileo, was an Italian physicist, mathematician, astronomer and philosopher. His achievements include improvements to the telescope and consequent astronomical observations, and support for Nicolaus Copernicus. His contributions to observational astronomy include the telescopic confirmation of the phases of Venus, the discovery of the four largest satellites of Jupiter (named the Galilean moons in his honour), and the observation and analysis of sunspots. Galileo's championing of Copernicanism was controversial within his lifetime, when a large majority of philosophers and astronomers still subscribed to the geocentric view that the Earth is at the centre of the universe. After 1610, when he began publicly supporting the heliocentric view, which placed the Sun at the centre of the universe, he met with bitter opposition from some philosophers and clerics, and two of the latter eventually denounced him to the Roman Inquisition early in 1615.
How did Galileo's oberservations of Jupiter's moons help to show that the geocentric explination is incorrect?
He discovered that they orbit around Jupiter, the first example of anything that did not orbit round the Earth, which lent support to the idea that the Sun might be at the centre of the solar system. After Galileo's lifetime, with further scientific discoveries, this was discovered to be true
How did Galileo and observation of Venus support the heliocentric?
Galileo's observations with his telescope supported the concept of heliocentricism. He noted that the satellites of Jupiter and Venus, based on their range of phases, did not match geocentricism supported by Ptolemy. He noted that based on these findings, that the Heliocentric theory was correct.
What were some of the important discoveries Galileo made with his telescope?
One important discovery was the four large moons of Jupiter, which Galileo was the first to observe and describe. He also discovered that they orbit around Jupiter, the first example of anything that did not orbit round the Earth, which lent support to the idea that the Sun might be at the centre of the solar system. After Galileo's lifetime, with further scientific discoveries, this was discovered to be true.
