Today was the first time in 99 years a total solar eclipse could be seen from coast to coast.
Portland, Oregon, went dark in the middle of the day as the shadow from the moon totally blocked the sun.
Millions of people drove to cities in the 70-mile-wide path of totality so they could witness history in person.
"It was very weird. Once the sun actually vanished, watching everybody scream and have a great time was a blast," said Chris Land.
It was darkest for two minutes and 40 seconds in Carbondale, Illinois.
That's longer than anywhere else in the country.
The next United States solar eclipse will be in 2024, but you won't be able to see that one coast to coast.
