Eddington studied the properties of a solar eclipse on various expeditions around the world. This research eventually confirmed Albert Einstein’s theory that as light passes a very massive star, its path is bent due to gravity.

Eddington spent a great amount of time researching the internal makeup of stars. One of his findings in this field was that the scattering of electrons is the primary source of the opacity of stars. Along with this finding, he also determined that a star’s luminosity if finite for a supplied mass.

In ancient China, the solar and lunar eclipses were regarded as heavenly signs that foretell the future of the Emperor; predicting eclipses were of high importance for the state. Over four millenniums ago, two Chinese astrologers were murdered as they failed to predict a solar eclipse.

The ancient Chinese believed that solar eclipses occur when a legendary celestial dragon devours the Sun. They also believed that this dragon attacks the Moon during lunar eclipses. In the Chinese language, the term for eclipse was “chih” which also means “to eat”. One ancient Chinese solar eclipse record describes a solar eclipse as “the Sun has been eaten”.
