If you’re nowhere near the path of totality or if clouds spoil your view, you can still catch the total solar eclipse online.

Weather permitting, tens of millions who live along a narrow stretch from Mexico's Pacific coast to eastern Canada can just look skyward Monday to glimpse day turn to twilight when the moon blots out the sun.

Eclipse glasses are a must to prevent eye damage. The only time it's safe to ditch protective glasses is during totality, or the few minutes of complete darkness.
