He made many experiments and observations in the field of physics in general.
Because the Catholic doctrine was that Rome was the centre of the universe and all things revolved round it. When Galileo saw the moons of Jupiter orbiting jupiter, this proved that Catholic teaching and beliefs were wrong and if this was wrong, what else about Catholic teaching may be wrong!
Although they are not considered "anamolies" now, at the time these observations did not fit into standard ideas about the cosmos: 1) Jupiter has moons. 2) The Milky Way consists of stars. 3) Venus has phases over time.
Galileo was named after an ancestor on his father's side, Galileo Bonaiuti. It was a common practice in Renaissance Italy to name children after their grandparents or other family members to honor their memory and establish a connection with family lineage.
Galileos discovery of those moons led people to realise that not everything in the universe moves round the Earth. It raised the question of whether the Sun travels round the Earth or not. A hundred years after Galileo's time, scientific discoveries were making it increasingly clear that the Sun is at the centre of the solar system.
He made many experiments and observations in the field of physics in general.
The branch of physics referred to as mechanics.
He challenged their authority by pointing out scientific errors that were being officially taught as fact.
The telescope
the Earth revolves around the Sun, which challenged the geocentric model of the universe. His discoveries also supported the heliocentric model proposed by Copernicus. Galileo's observations with the telescope provided evidence for this idea.
Found planets and satellites.
