Data gathered using Galileo's early telescope, such as observations of the phases of Venus and the moons of Jupiter, provided evidence supporting the heliocentric model. These observations showed that not all celestial bodies orbit the Earth, as previously believed, but instead supported the idea that they orbited the Sun. This challenged the geocentric view and provided observational proof for the heliocentric model proposed by Copernicus.
Galileo's early telescope observations provided crucial evidence for the heliocentric model by revealing celestial phenomena inconsistent with the geocentric view. He discovered the phases of Venus, which showed that it orbits the Sun, not the Earth, as the geocentric model suggested. Additionally, Galileo observed Jupiter's moons, demonstrating that not all celestial bodies revolve around the Earth. These findings supported the idea that the Sun is at the center of the solar system, with planets, including Earth, orbiting around it.
None of it but Galileo's discoveries with the telescope were very important in raising questions about the old Ptolemaic theory, which was geocentric. However Galileo's discovery of Venus's phases was not a proof of the heliocentric principle because Tycho produced a geocentric model that explained Venus's phases.
i think it's Kepler
This shift in understanding was largely due to the work of astronomers like Nicolaus Copernicus and Johannes Kepler, who proposed heliocentric models of the universe in the 16th and 17th centuries. Their theories were later confirmed by Galileo Galilei's observations using a telescope, which provided empirical evidence supporting the heliocentric model and eventually led to the acceptance of the idea that the planets orbit the sun.
Apex: conclusion
deductive
If a hypothesis is supported by new data gathered over a period of time, it may become a theory. A theory is a well-supported explanation that has been extensively tested and confirmed through observation and experimentation.
In telescopes that use them, mirrors are the principal mechanism of magnification. The mirror is what gathers the light, and the more light gathered the better. The eyepiece is not the principal magnifier; the eyepiece serves to focus the gathered light so that it can make a clear image on the retina. The larger the mirror, the more light is gathered, and the better the telescope is.

Bruno did a pretty good job of it, and was burned at the stake for his troubles. Galileo's observations of the solar system were very thorough, and he had a decent telescope with which to record his findings. The evidence Galileo gathered was quite compelling.
