The complete shrouding of our sun by the moon has mesmerized humanity for millennia — a moment in time when skies darken and stillness creeps in.

It’s spellbinding not only for the lucky ones in the path of total darkness, but also those on the fringes of the moon’s shadow getting a partial glimpse.

The cosmic curtain is about to rise again on the greatest show on Earth: a total solar eclipse that will dazzle tens of millions as it races across North America.

Day will turn into night as the moon perfectly positions itself between Earth and the sun on April 8, temporarily blocking the sunlight. The eclipse will begin in the Pacific, cross into Mexico and then cut through Texas on a northeasterly path through 15 states before heading out over Canada and the North Atlantic.

Totality will last up to 4 minutes, 28 seconds — enough time for the wonder of it all to soak in, weather permitting.
