Eclipse is a shadow either the Moon or Earth, he said in an interview Head of Astronomy and Space Luis Enrique Erro Planetarium of the National Polytechnic Institute (IPN), Wilder Chicana Nuncebay Sciences.
When the Earth stands in front of the Moon and casts its shadow A lunar eclipse occurs, so the Earth’s atmosphere acts as a lens, he said.
The solid part of our planet is a dark shadow called umbra, which in the Sunday eclipse will last three hours 19 minutes and the dim shadow, caused by the atmosphere, called penumbra.
During a total eclipse of the moon can not completely obscure the natural satellite of our planet, because although light does not pass the solid part of the Earth it does in the atmosphere, he said.
So “when there is a lot of pollution of suspended particles or volcanic ash, the color projected to have the moon is quite red” and so on This event will be also known as “moon of blood”.
“The less red is the moon, less polluted the Earth,” he said.
