On Saturday, April 4th, sky gazers in many parts of the world were treated to the third of the four lunar eclipses that will occur. What made the celestial event even more special is that it was the shortest one of the century.The eclipse of the moon occurs when earth gets in the way of the sun and moon. when our planet gets in between the two, its shadow falls on the moon, resulting in what we call, lunar eclipse. The length of the eclipse depends on what part of earth the moon is passing through.For lunar eclipses to occur there has to be a full moon and, the sun, earth and moon all have to be aligned perfectly. It is no wonder this rare string of tetrad successive total lunar eclipses (without intervening partial eclipses) is generating so much excitement and in some cases even fear.That's because thanks to the burnt-orange before, during and after the total eclipse, full lunar eclipses are sometimes referred to as "Blood Moons". However, according to NASA scientists lunar eclipses are a natural phenomenon that should be enjoyed without fear and can be viewed safely with the naked eye.
