A total solar eclipse will grace the skies over North America on Monday, one of the most hotly anticipated sky-watching events in recent years.
Weather permitting, millions of people in Mexico, 15 U.S. states and eastern Canada will have the chance to see the moon slip between Earth and sun, temporarily blocking the sun’s light.
The total solar eclipse will be visible along a “path of totality” that measures more than 100 miles wide and extends across the continent. Along that path, the moon will fully obscure the sun, causing afternoon skies to darken for a few minutes.
