A rare total lunar eclipse is set to take place on January 31 for the first time in over 150 years. This will be the second full moon of the month, also called the 'Blue Moon' and the first eclipse in the new year. The eclipse is a phenomenon that occurs when the Earth, moon and sun are in perfect alignment, blanketing the moon in the Earth's shadow, says NASA. In total lunar eclipse the direct sunlight is completely blocked by the earth's shadow. The total phase of this lunar eclipse, also known as a 'Blood Moon, will be visible in large parts of US, northeastern Europe, Russia, Asia, the Indian Ocean, the Pacific, and Australia.
