Which astronomical figure is known for using the telescope and contributing to our understanding of the solar system?

Galileo is renowned for his pioneering use of the telescope, which greatly advanced our understanding of the solar system. He was among the first to utilize this powerful instrument for astronomical observations, leading to significant discoveries such as the moons of Jupiter, the phases of Venus, and detailed observations of the Sun and the Moon's surface. His work provided strong evidence against the geocentric model of the universe and supported the heliocentric model proposed by Copernicus. By meticulously documenting his findings, Galileo not only expanded comprehension of planetary motions but also laid the groundwork for modern observational astronomy, demonstrating the value of empirical evidence in science. This marked a pivotal shift in how humanity perceives its place in the universe.
