Galileo Galilei was an Italian physicist, mathematician, astronomer, and philosopher. He was a brilliant scientist

HIS EARLY YEARS
Galileo was born in 1564 in Pisa, Italy. He was the first of six children of Vincenzo Galilei and Giulia Ammannati. His father was a famous musican.
Galileo's early education was in a monastery. From there, in 1581, he went to the University of Pisa, where he was a student of medicine and mathematics. Then from 1592 to 1610 he went to the University of Padua. He wasn't a student as this university – he was a professor of mathematics and astronomy.
Galileo was the father of three children – two daughters and a son – but he wasn't married to their mother.

HIS SCIENTIFIC LIFE
Galileo made excellent telescopes. With the he could see moons going round the planet Jupiter and the planet Venus going round the sun. At the time, there was the belief that the earth was the centre of the universe and the sun went round the earth. However , by 1610 Galileo's theory was that the earth was not the centre of our universe. Galileo said that the sun was the centre, and the earth moved round it.

HIS LAST YEARS
Some religious organisations weren't happy with Galileo's theories. His ideas were dangerous because they were different from the ideas in the Bible. Finally, in 1634 there was a trial. Galileo was 70 and not in good health so he wasn't sent to prison, but he couldn't leave his house in Florence. It was here that he died is 1642. He was 78 years old and completely blind.
