Total Lunar Eclipse

Tonight (at least if you are living in the right part of the World and if the weather cooperates) you will be able to observe a rare total lunar eclipse.

For this to occur the Sun, Earth & Moon must be aligned. The full moon will move into the Earth’s shadow so that all sunlight is blocked from reaching the moon’s surface.

If you are a looking from a light polluted area you will most likely only see the moon become “invisible”. However, if you are fortunate enough to live in an area that is not affected by light pollution then you could see the moon turn shades of copper, orange, or blood red. The effect is similar to the color changes observed during sunrises or sunsets, depending on clouds and dust in the atmosphere.

On a historical note, the type of lunar eclipse that we will observe tonight is the exact same type of lunar eclipse that saved Christopher Columbus and his crew during their 4th voyage in 1504.

Stranded on the coast of Jamaica, the explorers were running out of food and faced with increasingly hostile local inhabitants who were refusing to provide them with any more supplies.

Columbus, looking at an astronomical almanac compiled by a German mathematician, realized that a total eclipse of the Moon would occur on February 29, 1504.

He called the native leaders and warned them if they did not cooperate, he would make the Moon disappear from the sky the following night.

The warning, of course, came true, prompting the terrified people to beg Columbus to restore the Moon — which he did, in return for as much food as his men needed. He and the crew were rescued on June 29, 1504.

If you miss seeing the total lunar eclipse tonight, the next time you will be able to observe another (total) eclipse will be December 21, 2010.
