Vincenzo decided that his son should become a doctor.In 1581, Galileo was sent to the University of Pisa to study medicine.While a student at the university, Galileo discovered that he had a talent for mathematics. In 1609, Galileo heard about the invention of the spyglass, a device which made distant objects appear closer.

In 1609, Galileo heard about the invention of the spyglass, a device which made distant objects appear closer. Galileo used his mathematics knowledge and technical skills to improve upon the spyglass and build a telescope. Later that same year, he became the first person to look at the Moon through a telescope and make his first astronomy discovery. He found that the Moon was not smooth, but mountainous and pitted.

He subsequently used his newly invented telescope to discover four of the moons circling Jupiter, to study Saturn, to observe the phases of Venus, and to study sunspots on the Sun. Galileo's observations strengthened his belief in Copernicus' theory that Earth and all other planets revolve around the Sun.

. The Catholic Church, which was very powerful and influential in Galileo's day, strongly supported the theory of a geocentric, or Earth-centered, universe.. Early in 1616, Galileo was accused of being a heretic, a person who opposed Church teachings. Heresy was a crime for which people were sometimes sentenced to death. Galileo was cleared of charges of heresy. In 1632, he published a book that stated, among other things, that the heliocentric theory of Copernicus was correct. Galileo died on january 8 1642.


Lasting Impact

Galileo created his own model of the refracting telescope. He also discovered the mountains on the moon which we know now to have been made by asteroids colliding with the moon.


Birth & Death

Galileo Galilei was born on February 15 1564 in Pisa, Italy. He died on January 8 1642 in Arcetri, Itlay. When he died he was 78 and along with his dicoveries he will never be forgotten.

Galileo was an amazing astronomer who accomplished many things. He dicovered Jupiters moons Callisto, Europa, Ganymede, and Io. he also discovered the phases of venus confirming copernicus's heliocentric theory of the planets revolving around the sun.
