What has Quantum Mechanics Ever Done for Astronomy?

Quantum mechanics has had a profound impact on astronomy and astrophysics, enabling advancements in understanding the universe at both microscopic and macroscopic scales. For instance, quantum mechanics is crucial for the functioning of atomic clocks used in GPS satellites, which rely on the hyperfine transition of cesium atoms. This transition is an intrinsically quantum phenomenon, demonstrating the practical applications of quantum mechanics in everyday technology that also benefits astronomy.
