ScienceWhat can we learn from eclipses?

A total solar eclipse is set to cross northern Spain on August 12, making it one of Europe’s most anticipated astronomical events of the decade. These rare phenomena continue to offer scientists insights into the Sun’s corona, animal behaviour and human emotions. Their scientific value persists more than two thousand years after people first observed eclipses. Olivier Joie-La Marle, head of space science at the Centre National d'Études Spatiales, offers further perspectives.
