Rare 'Blood Moon' Lunar Eclipse Dazzles Sky-Gazers
Turn your gaze to the stars tonight for an eerie and spectacular view of
the "blood moon." At 12:53 a.m. ET, the Earth will begin to position
itself between the sun and the moon for the first of a series of four
total eclipses to conclude in September 2015.
The phenomenon is known as a tetrad, in which the moon is completely
covered by the earth's umbral shadow for four eclipses in a row, as
opposed to only partial eclipses that fall in the outer penumbra. But
rather than succumbing to complete darkness, the moon will glow red as
it receives the refracted light that spills over the Earth's
circumference.
