Galileo

Born in 1564 in Pisa, Italy, Galileo Galilei was a pioneering inventor and scientist, renowned for revolutionizing astronomy. He improved the telescope, achieving a magnification of 20x, and made groundbreaking celestial observations, including sunspots, moon craters, and the moons of Jupiter. His findings challenged the geocentric view of the universe, leading to conflict with the Catholic Church which deemed his ideas heretical. Despite his lifetime sentence of house arrest from 1616, his legacy persisted, culminating in NASA’s 1989 Galileo mission studying Jupiter.
