Galileo Galilei is often referred to as the "father of modern observational astronomy" due to his revolutionary use of the telescope to make astronomical observations that changed our understanding of the universe. His enhancements to the telescope allowed him to observe celestial bodies in greater detail than ever before. Notably, he discovered the four largest moons of Jupiter, known as the Galilean moons, which provided critical evidence against the geocentric model of the universe.

Galileo's observations of the phases of Venus and the detailed study of sunspots further supported the heliocentric theory and demonstrated that heavenly bodies were not perfect and immutable, as previously thought. His scientific method emphasized direct observation and experimentation, which became foundational elements of modern science. This rigorous approach set him apart from his predecessors, thereby earning him the title.

While Tycho Brahe made significant contributions to astronomy with his precise measurements and data collection, and Johannes Kepler formulated the laws of planetary motion, it was Galileo's blending of observational techniques with experimental methods that solidified his reputation as the father of modern observational astronomy. Nicolaus Copernicus, on the other hand, proposed the heliocentric model but did not conduct the kind of observational work that Galileo did.
