According to NASA, “a lunar eclipse occurs when the Sun, Earth, and Moon align so that the Moon passes into Earth’s shadow. In a total lunar eclipse, the entire Moon falls within the darkest part of Earth’s shadow, called the umbra."

Lowly Earthlings are about to get their first chance this year of seeing a lunar eclipse – including in London. North, South America and Europe will all see the rare astronomical event which causes a ‘Blood Moon’ next month. But depending on where on the planet you are will decide what kind of eclipse you see.
