ScienceSpain prepares for rare total solar eclipse

A rare total solar eclipse is due within hours, briefly turning parts of northern Spain from daylight to darkness as the Moon passes across the Sun. Millions of people in Europe, Canada, the northern United States and northwest Africa are expected to see a partial eclipse. Beyond the spectacle, such events give scientists useful opportunities to study the Sun and the universe. France 24 correspondent Sarah Morris reports from Segovia, Spain.
