Millions across North America to witness total solar eclipse

A total solar eclipse will invite millions of people across a heavily populated swath of North America to gaze toward the heavens today as the moon completely blocks the sun for more than four minutes in some locales.

The eclipse will be viewable, weather permitting, along a path starting in Mexico and then crossing through the United States and into Canada.

About 32 million people in the United States live within the path of totality, with federal officials predicting another 5 million people will travel to be there.

A partial eclipse will be visible in North America outside the path of totality.
