Total Solar Eclipse

The Exploratorium, a hands-on museum of science, art, and human perception in San Francisco, California, brings you live images of the sun during the total solar eclipses occurring on July 2, 2019 and December 14, 2020. On July 2, 2019, our team will aim telescopes at the eclipse from the National Science Foundation's Cerro Tololo Observatory in Chile to capture the event and livestream it to the world via our 2018 Webby Award-winning app.

This free app allows you to view three simultaneous video streams: 1) LIVE coverage hosted by Exploratorium educators and NASA scientists, 2) LIVE coverage in Spanish hosted by Exploratorium educators, and 3) a non-narrated, two and a half hour live telescope view of the full eclipse.

• Explore the path of totality of the 2019 eclipse and the 2020 eclipse with interactive maps and see the level of total eclipse you can observe from your location.

• Share livestream and past expedition videos.

• Follow the conversation on Twitter using #eclipse2019, #eclipse2020, #solareclipse, and #totalsolareclipse in the app's Twitter View and share your tweets about the eclipse.

• Watch and share videos that explain what an eclipse is and how to view an eclipse safely.

• Watch and share videos and explore maps from past Exploratorium eclipse expeditions including the 2017 eclipse that crossed the U.S.A. and the 2016 solar eclipse from Micronesia.

• Receive notifications about the eclipse.
