The moon slipped between the Earth and the sun on Saturday, casting a shadow on our planet in parts of the United States, Canada, the Caribbean, Europe, Russia and Africa.

During a partial solar eclipse, the moon passes between the sun and Earth. The moon casts a shadow on Earth and only partly blocks the sun, making it appear like a crescent. Unlike a total solar eclipse, there’s no totality so experts say proper eye protection must be worn the whole time.

Skygazers across a broad swathe of the Northern Hemisphere will have a chance to see the Moon take a bite out of the Sun on Saturday when a partial solar eclipse sweeps from eastern Canada to Siberia.
