Nicolaus Copernicus was the first to propose a heliocentric model of the solar system in the 16th century, which placed the Sun at the center with planets orbiting around it. Galileo Galilei supported Copernicus's ideas and used his observations through a telescope to provide further evidence for this model in the early 17th century.
Galileo first used the telescope to study planets in 1609, when he heard about the invention of the telescope in the Netherlands and built his own version of it. He observed the planets, including Jupiter and its moons, which led to significant advancements in the field of astronomy.
Galileo Galilei discovered that the Earth revolves around the Sun, not the other way around. This was a groundbreaking finding that supported the heliocentric model of the solar system proposed by Copernicus. Galileo's observations through his telescope also led to discoveries such as the moons of Jupiter and the phases of Venus.
Galileo did not prove that Earth was not flat (It had already been agreed that it was round). Galileo invented the telescope and used it to prove that there were objects which did not orbit the Earth, supporting Copernicus' Heliocentric model for the universe. The Earth was known to be round by the ancient Greeks, but I do not who it found out initially (sorry).
Nicolaus Copernicus is the astronomer who proposed the heliocentric model of the solar system in which the Earth and other planets revolve around the Sun. His work "De revolutionibus orbium coelestium" was published in 1543.
Copernicus, with the use of the heliocentric theory and Galileo with his telescope proved the planets revolve around the Sun.

Nicolaus Copernicus, Galileo Galilei, and Johannes Kepler were prominent scientists who challenged the Earth-centered view of the universe, known as the geocentric model. Copernicus proposed the heliocentric model, where the Earth and other planets orbit around the Sun. Galileo's observations with the telescope provided evidence for this heliocentric model, while Kepler refined it by discovering that planets move in elliptical orbits around the Sun.
Galileo disproved the notion that the Earth was the center of the universe by observing the phases of Venus through a telescope, which supported the heliocentric model proposed by Copernicus. This provided evidence that Earth and other planets revolve around the sun, not Earth being the center of the universe.

Galileo's observations through his telescope suggested that planets had substance, challenging the prevailing belief that they were simply points of light in the sky. He saw that they had features like the moon, such as phases and changing appearance, supporting the idea that they were physical bodies. This went against the geocentric model of the universe and contributed to the acceptance of the heliocentric model proposed by Copernicus.
