Millions of people across North America are turning their gaze toward the sky on Monday to catch a glimpse of the total solar eclipse. For those who are unable to view the celestial event in person, Yahoo News will be streaming live video footage from across the path of totality.

People near Mazatlán, Mexico were the first to see the partial eclipse as it emerged on the continent at 12:51 p.m. ET. The highly anticipated celestial spectacle will then continue along a “path of totality” that will span more than 100 miles across the width of the continent.

In the U.S., the sun will be fully obscured for a few minutes in 15 states, from Texas to Maine, but the eclipse will be at least partially visible — weather permitting — in 49 states. Alaska is the only state where the eclipse won’t be visible this time around.
