On December 14, 2020, the Exploratorium continues its 20-year tradition of bringing live images of eclipses to you—we’re traveling to Villarrica, Chile, in the lake district of Patagonia, to broadcast a total solar eclipse visible overhead from parts of South America. Experience the wonder wherever you are: enjoy our live broadcast, available in both English and Spanish on our free iOS and Android apps and this website.

Telescope and live coverage feeds will also be available via satellite in North and South America.
To view the 2020 total solar eclipse, you’ll have to be somewhere within the blue and red stripe stretching across the countries of Chile and Argentina on this map. This “path of totality,” where the darkest part of the moon’s shadow hits the Earth, is only 70 miles wide. Viewers outside that band will see a partial eclipse.
Join Exploratorium astronomer Isabel Hawkins and Exploratorium educator Liliana Blanco as they explain the celestial mechanics of a total solar eclipse. Through demonstrations, they show how the moon, sun, and Earth align to create the cosmic coincidence that we see as a total solar eclipse. En Español
