he observed the moons of Jupiter and saw that the moons went around Jupiter not the earth. he knew this because one disappeared behind the planet every once in a while and it was never the same one over and over again.
Galileo
Galileo expressed his support of the Copernican theory that the Earth and planets revolved around the Sun. But that wasn't exactly a trial.
The Copernican Hypothesis is the hypothesis that the sun, rather than the earth, was at the centre of the universe. Copernicus theorised that the stars and planets, including the earth, revolved around a fixed sun. He worked on it from 1506-1530, but it wasn't published until the year of his death in 1543.
Although Galileo's telescope was the first to be used for astronomical purposes, he didn't invent the telescope. A man named Hans Lipperhey invented the telescope. Many people claimed to have invented the telescope however Hans Lipperhey was the only one to apply for a patent.
Heliocentrism is the "truth" discovered by Galileo that is depicted burning in the fire with him. Heliocentrism is the idea that Earth and the other planets in our galaxy revolve around the Sun. The fire in the picture represents the sun, with the surrounding people representing the planets and the Earth's moon. Hope this helped!
Galileo's observation was that all the planets revoled around the earth and he though earth was a middle planet

He discovered that the planets revolved around the sun instead of the planets & the sun revolving around Earth.

Pre-Galileo, no planets revolve around earth
Galileo thought planets revolved around the sun because when he observed Jupiter, he noticed that its moons revolved around Jupiter and not earth. So everything else led up to that the Earth revolved around the sun.
The concept that all planets revolve around Earth is known as the geocentric model. This idea was proposed by early astronomers before the heliocentric model, with Copernicus and Galileo helping to advance the understanding that Earth and other planets actually revolve around the Sun.
