The end of the world stands before us. At least if it is believed the calculations of the Mayan calendar, 21 December 2012 is the day on which all life on earth ends. Whether this day, where the annual winter solstice takes place, actually is the last day?
From the astronomical point of view, what out of the ordinary can be observed in fact to. A very unusual and rare planetary alignment ensures that the Sun in this some day occupies the center of the milky way. This is only about every 26,000 years and is caused by the oblique Earth’s axis, which rotates once circular. source
