Biography Of Galileo Galilei

Galileo Galilei once said “All truths are easy to understand once they are discovered; the point is to discover them.” Born in Pisa, Italy on February 15, 1564 Galilei was an Italian astronomer, mathematician, and physicist. Who then died on January 8, 1642. He was a man of many talents who was able to invent his own telescope. He invented his first telescope in 1609, Galileo built on the work of others to create a telescope with around 3x magnification, he later improved on this to make telescopes with around 30x magnification. He was also put on trial by the Holy Office and was ordered to turn himself in for holding the belief that the Earth revolves around the Sun, which was deemed heretical by the Catholic Church.

According to my source it states that, “With this telescope, he was able to look at the moon, discover the four satellites of Jupiter, observe a supernova, verify the phases of Venus, and discover sunspots.”
