A lunar eclipse versus a solar eclipse
Today’s Video of the Day from the European Space Agency describes the difference between a solar and a lunar eclipse.
A solar eclipse occurs when the moon moves between our planet and the sun, where it blocks sunlight and casts its shadow over the Earth.
A lunar eclipse, on the other hand, takes place when the Earth blocks the sunlight that is usually reflected off the moon.
The most dramatic of these events is called a total lunar eclipse, when the moon is completely engulfed by Earth’s shadow and the light that reaches the moon appears “blood red” as it is filtered by our atmosphere.
The total lunar eclipse that occurred on July 27th was the longest of this century.
