In 1781, William wasn't just viewing stars; he spotted something different! π
He was using his telescope in Bath, England, when he discovered a new planet called Uranus! Before this, people only knew of five planets: Mercury, Venus, Mars,
Jupiter, and Saturn. π
The discovery of Uranus changed astronomy because it expanded our understanding of the solar system. Herschel thought it was a comet at first, but later found out it was a planet! This was an exciting moment in science history and made Herschel famous! π
