Eddington 1919 solar eclipse expedition

E236240

The Eddington 1919 solar eclipse expedition was a landmark astronomical observation campaign that measured the deflection of starlight by the Sun’s gravity, providing the first major empirical confirmation of Einstein’s theory of general relativity.
