His contributions to observational astronomy include telescopic confirmation of the phases of Venus, observation of the four largest satellites of Jupiter, observation of Saturn’s rings, and analysis of sunspots .
What was Galileo’s greatest contribution?
Of all of his telescope discoveries, he is perhaps most known for his discovery of the four most massive moons of Jupiter , now known as the Galilean moons: Io, Ganymede, Europa and Callisto. When NASA sent a mission to Jupiter in the 1990s, it was called Galileo in honor of the famed astronomer.
What 3 important discoveries did Galileo make?

Galileo’s Contributions to Science
He is best known for his astronomical observations, which included the features of the Moon, the phases of Venus, four of Jupiter’s moons , and Sunspots, as well as for the then radical theories that flowed logically from those observations.
What 5 things did Galileo?

- The phases of Venus. ...

- The first pendulum clock.
Who discovered Earth?
Eratosthenes then measured the angle of a shadow cast by a stick at noon on the summer solstice in Alexandria, and found it made an angle of about 7.2 degrees, or about 1/50 of a complete circle. He realized that if he knew the distance from Alexandria to Syene, he could easily calculate the circumference of Earth.
What did Galileo say about gravity?
According to legend, Galileo dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration .
Who is the father of science?
Albert Einstein called Galileo the “father of modern science.” Galileo Galilei was born on February 15, 1564, in Pisa, Italy but lived in Florence, Italy for most of his childhood. His father was Vincenzo Galilei, an accomplished Florentine mathematician, and musician.
What did Galileo contribute to society?
Galileo was a natural philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion, astronomy, and strength of materials and to the development of the scientific method. He also made revolutionary telescopic discoveries, including the four largest moons of Jupiter.
Who first discovered heliocentrism?
Nicolaus Copernicus was a Polish astronomer known as the father of modern astronomy. He was the first modern European scientist to propose that Earth and other planets revolve around the sun, or the Heliocentric Theory of the universe.
Who thought the earth was the center of the universe?

What is the first step of the scientific method?
The first step in the Scientific Method is to make objective observations . These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.
Did the Catholic Church invent the scientific method?
Catholic scientists, both religious and lay, have led scientific discovery in many fields . ... During the Middle Ages, the Church founded Europe’s first universities, producing scholars like Robert Grosseteste, Albert the Great, Roger Bacon, and Thomas Aquinas, who helped establish the scientific method.
