Galileo did not directly provide evidence for the heliocentric principle but he did discover important evidence that raised doubts about the Ptolemaic system with the Earth at the centre.
First, he discovered the moons of Jupiter, and these were the first objects discovered that definitely orbited round something that was not the Earth. That was one thing.
Secondly, he discovered that Venus has a gibbous phase when seen from Earth in certain positions in its orbit. This is not explained by the Ptolemaic system because Venus cannot go round behind the Sun in the Ptolemaic system.
Again this did not prove the heliocentric principle because Tycho Brahe came up with an intermediate system that had Mercury and Venus orbiting round the Sun, and then the Sun and the other planets orbit round the Earth. So this was still a geocentric system that explained all Venus's phases.
Therefore Galileo did not have enough evidence to prove the heliocentric principle, and after his trial he recanted.
But 60-70 years later enough new evidence had been gathered to convince most people that the Sun is at the centre, as we believe now.
Galileo developed the telescope, which allowed him to observe celestial bodies such as the moons of Jupiter and the phases of Venus. These observations provided evidence to support the heliocentric theory proposed by Copernicus.
Copernicus' heliocentric model provided the framework for Galileo to further explore and confirm through his observations with the telescope. Galileo's discoveries, such as the moons of Jupiter and the phases of Venus, provided empirical evidence in support of the heliocentric model and contributed to its acceptance over the geocentric model.
Galileo discovered the moons of Jupiter and observed the phases of Venus, providing evidence to support the heliocentric model of the solar system. Herschel discovered the planet Uranus and infrared radiation, expanding our understanding of the universe.

The Jovian moons. Galileo had little evidence for the heliocentric theory, which was later (in the 18th century) generally accepted as correct after the laws of motion and the law of gravity showed that the Sun is by far the most massive object in the solar system and therefore must be at the centre. Galileo did not have the other major piece of evidence supporting the heliocentric theory, which is the parallax shown by relatively close stars as the Earth moves round its orbit. Parallax is extremely small and was impossible to observe in Galileo's time, and this was used to support the idea that the Earth is at the centre. Bessel made the first measurements of parallax in the 19th century.
One notable astronomer during the Renaissance was Nicolaus Copernicus, who developed the heliocentric model of the universe. Another significant astronomer was Galileo Galilei, who made important observations with the newly invented telescope, providing evidence in support of the heliocentric theory.

The telescope
Galileo Galilei is the astronomer who is credited with inventing the telescope and using it to support the heliocentric theory proposed by Copernicus. He observed the moons of Jupiter, sunspots, and phases of Venus, providing evidence for a Sun-centered solar system.
Yes, Galileo and Newton built upon Copernicus' heliocentric theory of the universe by providing further evidence and support through their own observations and laws of motion. Galileo's telescopic observations confirmed Copernicus' model, while Newton's laws of motion and universal gravitation explained the physical principles behind the heliocentric system.
Galileo
Galileo Galilei is credited with inventing the telescope and using it to support the heliocentric view of the universe proposed by Copernicus. Galileo's observations of the phases of Venus and the moons of Jupiter provided evidence for the motion of celestial bodies around the sun.
Galileo Galilei supported the heliocentric model of the universe, which posits that the Earth and other planets revolve around the Sun. This model, originally proposed by Nicolaus Copernicus, challenged the prevailing geocentric view that placed the Earth at the center of the universe. Galileo's observations, such as the phases of Venus and the moons of Jupiter, provided strong evidence for the heliocentric theory. His support for this model was pivotal in the scientific revolution, despite facing significant opposition from the Church and contemporary scholars.
