The most important discovery Galileo made to support the heliocentric model was his telescopic observation of the phases of Venus. From Earth, Venus appears in phases like those of the moon's - new, waxing crescent, waxing gibbous, full, waning gibbous, and waning crescent. In the Ptolemaic model Venus is never on the far side of the sun from Earth, and so it would never display the gibbous or full phases. On his first observation to check for Venusian phases he saw a gibbous Venus at once invalidating the Ptolemaic model. Over several months he continued his observations and saw Venus changing phase to half, and waning crescent confirming that Venus orbited the sun.
Galileo's discoveries and writings, particularly his support for the heliocentric model of the solar system, played a significant role in making him famous. Additionally, his conflicts with the Catholic Church and subsequent trial also brought attention to his work and ideas.
Galileo was formally exonerated by the Catholic Church in 1992. This exoneration came more than 350 years after he faced condemnation for his support of the heliocentric model of the solar system.
Galileo Galilei is most famous for his development and improvement of the telescope, his support of the heliocentric theory proposed by Copernicus, his discoveries in astronomy (such as the moons of Jupiter and sunspots), and his struggle with the Catholic Church over his beliefs.
Galileo made several important discoveries with his telescope, including the four largest moons of Jupiter (now known as the Galilean moons), the phases of Venus, sunspots on the Sun, and mountains and craters on the Moon. These observations provided evidence to support the heliocentric model of the solar system and challenged the geocentric view of the universe.
Nicolaus Copernicus and Galileo Galilei were both pivotal figures in the development of the heliocentric model of the solar system, but their contributions were distinct and occurred in different contexts. Copernicus proposed the heliocentric theory in the early 16th century, suggesting that the Sun, rather than the Earth, was at the center of the universe. Galileo, in the early 17th century, provided observational evidence to support Copernicus's model through his telescopic discoveries, such as the moons of Jupiter and the phases of Venus. While Copernicus laid the groundwork, Galileo advanced and defended the heliocentric view against significant opposition from the Church and contemporaries.

Galileo's most important invention was the telescope, which he used to make groundbreaking astronomical observations that supported the heliocentric model of the solar system. His discoveries revolutionized our understanding of the universe and sparked the scientific revolution.
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.
Galileo's discoveries, such as his observations of the moons of Jupiter and the phases of Venus, challenged the traditional beliefs of astrology. His findings supported the heliocentric model of the solar system, which contradicted the geocentric views held by astrologers. This led to a decline in the credibility and popularity of astrology as a scientific practice.
