One of the most spectacular space sights visible from the Earth swept across the US on Monday.
Millions of people enjoyed an incredible total solar eclipse.
A total solar eclipse happens when the Moon moves in between the Earth and the Sun, blocking out the Sun’s light and plunging areas of the Earth into darkness.
It was called the Great American Eclipse, as the shadow cast on the Earth by the Moon fell directly onto America – so this was the best place to watch the eclipse.
It’s the first total solar eclipse the US has experienced since 1979, and the US’s first coast to coast solar eclipse since 1918.
During the total solar eclipse there’s a noticeable drop in temperature as the sun disappears. The darkness lasts for about two to three minutes.
Eclipse watchers are advised to wear special glasses and to avoid looking directly at the sun, to avoid eye damage.
The next coast-to-coast total solar eclipse will not be until 2045.
