Total solar eclipse (2/4) A total solar eclipse will sweep across northern Spain on August 12 in one of Europe's most anticipated astronomical events of the decade. From the Sun's corona to animal behaviour and human emotions, these rare celestial events continue to provide scientists with valuable insights more than two millennia after they were first observed.
Eclipses tell the story of humanity's relationship with knowledge. Once seen as dire omens, they have become open-air laboratories, feared for centuries and now closely studied by scientists in a continuity stretching back to the earliest observations of Antiquity.
