On Dec. 21, 2012, many doomsday believers fear the apocalypse — anything from a rogue planet smashing into us to our world spinning end over end. However, the world should expect nothing more next year than the winter solstice, the longest night of the year, NASA says.

Many people point to the end of the Mayan Long Count calendar on Dec. 21, 2012 as evidence of the coming apocalypse, but astronomers have been quick to stress that there is nothing to be concerned about.

According to the ancient Mayan calendar, next year’s winter solstice marks the end of a 144,000-day cycle. This cycle, which begins at the mythical Maya creation date, has already been repeated 12 times. The 13th will end in 2012, capping a full 5,200-year Mayan cycle of creation.

This date has long been shrouded in mystery, with many claiming that it will bring destruction to our planet.
