The United States is in the middle of one of her most historic events in decades, and it's not about politics.

The U.S. is experiencing a total solar eclipse that spans the entire Lower 48 today for the first time in nearly 80 years. Celebrities and politicians are taking to Twitter (TWTR - Get Report) to share excitement and rejoice in something that unifies the U.S. in a tumultuous geopolitical climate.

Famed astrophysicist Neil deGrasse Tyson highlighted unity:

The divided United States of America will unite today, sharing a cosmic event predicted by the methods and tools of science.

While Bruce Springsteen used safety tips as a thinly veiled self-promotion:

Remember to wear proper glasses today when viewing the #SolarEclipse. You don't want to get...

David Spade and Paris Hilton took on the eclipse-glasses-mania as well:

And actor Joseph Gordon-Levitt reminds us to look down, too:

Trees making pinholes. Sun shining through casts shadow crescents. (Basically how a camera works) #SolarEclipse2017

McDonald's Corp (MCD - Get Report) also had some eclipse-themed advertising today:

And of course, Bonnie Tyler's smash hit "Total Eclipse of the Heart" is having a big day 34 years after it was first released:

And first daughter Ivanka Trump shed some light:

Wondering how it works? In a solar #eclipse, the moon passes between the  Sun & Earth & blocks all or part of the sun for up to about 3 hrs.

But it seems not all politics could be left out of the unifying cosmic event, as Twitter users trolled Ivanka after she tweeted the basic infographic:

That's longer than most White House employees last.
