Happy 142nd Birthday to Arthur S. Eddington, a prominent British astronomer and physicist of the 20ᵗʰ century. He is best known for his observational confirmation of Albert Einstein's theory of general relativity. In 1919, during a solar eclipse, Eddington led an expedition that observed the bending of starlight around the Sun, providing empirical evidence supporting Einstein's theory that massive objects cause a distortion in space-time.

Eddington was also the first to propose that stars obtain their energy from nuclear fusion processes, a groundbreaking concept at the time. This insight laid the foundation for all subsequent theories about how stars generate energy and evolve over time.
