What notable contribution did Tycho Brahe make to astronomy?

Tycho Brahe made significant strides in the field of astronomy, particularly through his meticulous observational work. His most notable contribution was the detailed observations of a supernova, which he referred to as a "new star," in 1572. This event challenged the prevailing belief that the heavens were unchanging and immutable, which was a fundamental concept in astronomy at the time.

Brahe's careful observations, which did not rely on telescopes but rather on large, precise instruments he designed himself, allowed him to document the behavior and properties of celestial bodies with unprecedented accuracy. His work laid the foundation for future astronomers like Johannes Kepler, who would later use Brahe's data to develop his own theories about planetary motion, including the laws of planetary orbits. This marked a pivotal shift in the scientific understanding of the universe, moving from a geocentric view to a heliocentric one and ultimately supporting the concepts of modern astronomy.

Other options refer to contributions made by different astronomers or developments in the field that occurred later, such as the discovery of universal gravitation by Isaac Newton or the concept of elliptical orbits proposed by Kepler based on Brahe’s data. The use of telescopes for astronomical observations was popularized later by
