He is possibly most remembered for discovering Jupiter's four most massive moons, today known as the Galilean moons: Io, Ganymede, Europa, and Callisto, with his telescope. What was the name of Galileo Galilei's father? Vincenzo Galilei, an acclaimed Florentine mathematician and musician, was his father. Galileo studied medicine at the University of Pisa from to but dropped out without receiving a diploma, instead of going to Florence to coach mathematics.
How many years did Galileo live for? Galileo, who was nearly 70 years old at the time of his trial, spent the remaining nine years of his life behind house arrest, creating a summary of his early motion experiments that would later become his final great scientific opus. He died on January 8, , at Arcetri, near Florence, Italy, at the age of 77, after suffering from heart palpitations and fever.

CBSE Notes. CBSE Notes for class This marked the rebirth of the telescope, which had been virtually unknown for nearly twenty years, and became a powerful tool for scientific inquiry. Therefore, Galileo can be considered the inventor of the first telescope. He quickly improved his telescope, and according to his own words, "built an instrument so perfect that objects appeared almost a thousand times larger and more than thirty times closer than when observed with the naked eye".
Galileo turned his telescope towards the sky on the night of January 7, What he saw there — the lunar landscape, mountain ranges and peaks — led him to believe that the Moon resembled the Earth and had mountain systems. This discovery contradicted religious dogma and Aristotle's teachings about the special position of Earth among celestial bodies.
Galileo also discovered four moons of Jupiter, which also contradicted Aristotle's teachings. He established that the Sun rotates on its axis. Based on his observations, Galileo concluded that rotational motion was inherent to all celestial bodies and that the heliocentric system proposed by Copernicus was the only true one.
Galileo began to advocate more boldly for Copernican theory. In , eleven prominent theologians reviewed Copernican theory and concluded that it was false. Galileo was summoned from Florence to Rome and ordered to cease propagating heretical views on the structure of the universe. In , Galileo wrote a letter to a student to explain how Copernican theory did not contradict Biblical passages, stating that scripture was written from an earthly perspective and implied that science provided a different, more accurate perspective.
The letter was made public and Church Inquisition consultants pronounced Copernican theory heretical. Galileo obeyed the order for seven years, partly to make life easier and partly because he was a devoted Catholic. He allowed Galileo to pursue his work on astronomy and even encouraged him to publish it, on condition it be objective and not advocate Copernican theory.
Church reaction was swift, and Galileo was summoned to Rome. During most of this time, Galileo was treated with respect and never imprisoned.

However, in a final attempt to break him, Galileo was threatened with torture, and he finally admitted he had supported Copernican theory, but privately held that his statements were correct. He was convicted of heresy and spent his remaining years under house arrest. Though ordered not to have any visitors nor have any of his works printed outside of Italy, he ignored both.
In , a French translation of his study of forces and their effects on matter was published, and a year later, copies of the Dialogue were published in Holland. By this time, Galileo had become blind and was in poor health. In , it lifted the ban on most works supporting Copernican theory. It wasn't until that the Vatican dropped its opposition to heliocentrism altogether.
In the 20th century, several popes acknowledged the great work of Galileo, and in , Pope John Paul II expressed regret about how the Galileo affair was handled. Galileo died after suffering from a fever and heart palpitations on January 8, , in Arcetri, near Florence, Italy.
