Spain prepares for rare total solar eclipse

Summary

Millions more will see a partial eclipse across Europe, Canada, the northern US and northwest Africa. But beyond the spectacle, eclipses also offer scientists valuable insights into the Sun and our universe. France 24 correspondent Sarah Morris reports from Segovia, Spain.
