Total lunar eclipse,computer artwork. A lunar eclipse occurs as the Moon (far right) passes into the shadow of the Earth (centre),meaning that the light from the Sun (left) cannot reach it. Lunar eclipses occur only at full Moon,and then only when the Earth and full Moon are correctly aligned (about 2-3 times a year). The Moon's speed through the shadow is about one kilometre per second,meaning totality may last up to 107 minutes | |
