Total lunar eclipse

Total Lunar EclipseA dark red shadow crept across the moon Saturday during the first total lunar eclipse in nearly three years, thrilling stargazers and astronomers around the world.

A lunar eclipse is when the Earth gets between the Sun and the Moon so stops the Moon being illuminated. Actually, the Moon does get illuminated because the Earth's atmosphere acts as a lens to bend some light around onto the Moon. As the only light reaching the Moon has gone through our atmosphere, most of the blue light will be filtered out so the Moon will probably look orange or red.

The eclipse is visible from most of the planet apart from New Zealand, eastern Australia, Japan, Alaska and most of the Pacific.
