GENERAL KNOWLEDGE

Detailed explanation-1: -Galileo’s discoveries about the Moon, Jupiter’s moons, Venus, and sunspots supported the idea that the Sun-not the Earth-was the center of the Universe, as was commonly believed at the time. Galileo’s work laid the foundation for today’s modern space probes and telescopes.

Detailed explanation-2: -The discoveries that Galileo made using his telescopes helped to prove that Sun was the centre of the Solar System and not the Earth. His observations strongly supported a Sun-centred model known as the Heliocentric model, previously suggested by astronomers like Nicolaus Copernicus.

Detailed explanation-3: -Nicolaus Copernicus proposed his theory that the planets revolved around the sun in the 1500s, when most people believed that Earth was the center of the universe.

Detailed explanation-4: -Galileo discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter.
