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 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.

KRONOS STRING QUARTET
Like, in fine print, one of the last features of this app is "live sonofication on the eclipse by the Kronos String Quartet."
This is the app for me! Especially because chances are strong that I'll be inside since I nanny an infant. And I also don't have eclipse viewing glasses.
But to listen to the Kronos String Quartet play along to nuclear fusion occurring in the sun as the eclipse happens?! Too exciting! The coolest part of this app being undermarketed is a shame.
More Explo greatness.
I have had so much fun with this app already. Loads of entertaining and useful information. So easy to use and navigate (I'm a stickler for user experience).
Kudos to the whole Exploratorium team for their great work!
Waste time: just self-promoting ad, nothing new nor special!
There are already couple apps dealing with this 2017 solar eclipse. This new app offers nothing more than a simulation video and bunch of advertisers for certain live telecasts during this event. It does not help you to figure out your local viewing condition, position, or time, etc. Nor does it offer any safety tips or useful tools on how to observe this event. The app presentation is also poor with limited usefulness in the front page. I will pass this and delete it.
With Family Sharing set up, up to six family members can use this app.
