On May 29, 1919, the Moon slid in front of the sun and forever altered our understanding of spacetime. It was “Einstein’s Eclipse.” Using his newly-developed theory of relativity, the young German physicist predicted that the sun’s gravity should bend starlight–an effect which could only be seen during a total eclipse. Some of the greatest astronomers of the age rushed to check his prediction.
More than 100 years later, Petr Horálek (ESO Photo Ambassador, Institute of Physics in Opava) and Miloslav Druckmüller (Brno University of Technology) have just released a stunning restoration of the photo that proved Einstein right. The original picture was taken in May 1919 by astronomers Andrew Crommelin and Charles Rundle Davidson, who traveled from the Greenwich Observatory in London to the path of totality in Sobral, Brazil. They were part of a global expedition headlined by Sir Arthur Eddington. Glass photographic plates from the expedition were typical of early 20th century astrophotography, colorless and a little dull. Read More
