Americans gazed upwards in their millions on Monday, as a total solar eclipse swept the country.
It was the first such eclipse to go from the west to east coasts of the US in 99 years.
From schoolchildren in Missouri to mounted patrol officers in Idaho, the nation was transfixed by the sight of the Moon drifting in front of the Sun, and blocking its light.
Warnings had been made about eye safety in the build-up to the eclipse, with people told they should not look at the Sun directly with the naked eye, and instead wear special protective eyewear.
The US President, for his part, did not set the best example. (Though he and the First Lady were also pictured wearing protective eyewear.)
