One of the biggest social media moments of 2017, Monday’s solar eclipse, which was visible throughout North America, also became a top moment for video and one of the largest livestreamed events ever on YouTube.

From news organizations to educational institutions, a multitude of channels livestreamed the eclipse on YouTube. By 10:20 a.m. PT on Monday, more than 2 million viewers were simultaneously tuned in to these livestreams, including NASA’s, which was the most-watched.



In all, viewers watched livestreams and videos about the eclipse over 100 million times and for 6 million hours since Monday morning. Some people recorded their own time-lapses, 360 videos, and personal vlogs of the experience, and instructional videos on eclipse viewing were a favorite as well, like ”How to Make a Pinhole Projector to View the Solar Eclipse” (1.8 million views Monday) and ”Make a solar eclipse viewer at home with a cereal box” (580,000 views).

Some viewers used YouTube to celebrate the eclipse in a different way: through music. We saw a major spike in viewership of Bonnie Tyler's "Total Eclipse of the Heart" -- the official video was viewed over 1.6 million times yesterday, with hourly views reaching as high as 260,000 -- which was also the song we saw people adding most frequently to "Eclipse"-related playlists in the lead-up. (The rest of the top 5 included Creedence Clearwater Revival's "Bad Moon Rising,” Katrina and the Waves' "Walking On Sunshine," Owl City's "Galaxies," and Smash Mouth's "Walkin' on the Sun," respectively.)



If you didn't get to see the eclipse (or couldn't get your hands on some eclipse glasses), you can watch plenty of replays like these.
