| December 21, 2010 Lunar Eclipse by Jiyang Chen |
A lunar eclipse occurs when the Moon passes behind the Earth so that the Earth blocks the Sun's rays from striking the Moon. This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon. The type and length of an eclipse depend upon the Moon's location relative to its orbital nodes. The most recent total lunar eclipse occurred on December 10, 2011. The previous total lunar eclipse occurred on June 15, 2011; The recent eclipse was visible from all of Asia and Australia, seen as rising over Europe and setting over Northwest North America.
