Eclipse 2017: See what your favorite celebs are tweeting

In case you didn't already know, the eclipse that's happening today is a big deal: the continental United States is experiencing a total solar eclipse for the first time since 1979, and it's crossing from coast to coast — Bonnie Tyler is even performing her '80s hit "Total Eclipse of the Heart" for the occasion. During the eclipse, the moon will completely block the sun, and some parts of the country will experience sudden darkness. Ooooooooh.

This specific eclipse has been dubbed "The Great American Eclipse" and, as what oft happens when momentous things occur, celebs are talking about it all over social media. Don't worry if you forgot to get your special glasses for today's total solar eclipse — Sarah Hyland did too.
