In 2013, there will be three lunar
eclipses – a 27-minute partial on April 25-26, and two penumbrals. The 2013
lunar eclipses will be interesting, as always, despite the fact that none will
be total.
The April full moon will pass through Earth's shadow in a partial
lunar eclipse on Thursday (April 25). Its main distinction is that it’ll be the
third-shortest partial lunar eclipse of the 21st century. Only a tiny sliver of
the moon will be covered by the Earth’s umbral shadow at maximum eclipse.
Today's lunar eclipse
may be the best lunar eclipse of 2013, but will not be as impressive as
stunning total lunar eclipse, in which the entire moon is obscured by
Earth's shadow. This image of the lunar eclipse in December 2009 (the "blue moon") suggests what the April 2013 eclipse will look like. During total lunar eclipses, the moon can take on a
blood-red hue due to light refracted by the Earth's atmosphere. The
April 25, 2013 partial lunar eclipse will be visible over Europe, Africa, Asia,
and Australia. The next total lunar eclipse will be April 15, 2014.
What is a Lunar Eclipse? A Lunar Eclipse occurs when the Moon passes
through the shadow of the Earth. For this to happen the Sun, Earth, and
Moon must be closely aligned with the Moon and the Moon located furthest
from the Sun. There are a few different types of Lunar Eclipse that are determined by where the moon is in relationship to the shadow of the Earth.
