Lunar eclipse. Time-lapse image of a total eclipse of the Moon, a phenomenon caused when the Moon enters the shadow cast by the Earth. Even when totally shadowed the Moon does not generally disappear. It is still visible due to the sunlight refracted onto its surface by the Earth's atmosphere. The colour of the lunar disc during an eclipse depends on the amount of dust and volcanic ash present in the atmosphere of the Earth. This is because these particles scatter blue light, making the sunlight appear red. Photographed on 9 December 1992 over Lewes in Delaware, USA.
