A Century of Shadows
Over the past 100 years, humanity has chased solar eclipses across continents and oceans. Advances in technology, from early photography to satellite tracking, have allowed us to study the Sun's corona and validate fundamental laws of physics, including Einstein's Theory of General Relativity.
