What are the achievements in astronomy?

Answer 1

The biggest achievement in astronomy I believe is the first use of the telescope to study the sky byGalileo starting in 1609. He discovered the rings of Saturn, the 4 big moons of Jupiter and the phases of Venus. Then there is Copernicus and his heliocentric theory, published in the 1540's, stating that the sun was the center of the solar system, not the Earth. Kepler's theory of planetary motion, that completely did away with the need for epicycles, but suggesting correctly that planetary orbits are elliptical was the next great achievement.

Answer 2

Some major achievements in astronomy include the discovery of exoplanets beyond our solar system, the detection of gravitational waves, the mapping of the cosmic microwave background radiation, and the confirmation of the expansion of the universe. These milestones have greatly advanced our understanding of the cosmos and continue to shape our knowledge of the universe.
