Скачать или смотреть Light Scattered By Earth's Atmosphere

As light passes by the Earth's atmosphere, short wavelengths, like blue, are scattered. By the time light finishes its trip to the moon, only longer wavelengths, like red, remain. This is why the moon turns red during an eclipse! Credit goes to TheWusa from de.wikipedia.org for the illustration this animation is based on.


When the moon passes through the Earth's shadow, it causes the moon to look very unusual for a short period of time. This event is called a lunar eclipse, and it occurs roughly twice a year. Learn more about how lunar eclipses work in this video!
