On December 21, 2012, an event will occur that only happens once every 26,000 years. It's called the "Galactic Alignment." The Galactic Alignment is the alignment of the December solstice sun with the Galactic equator. This alignment occurs as a result of the precession of the equinoxes.
Precession is caused by the earth wobbling very slowly on its axis and shifts the position of the equinoxes and solstices one degree every 71.5 years. Because the sun is one-half of a degree wide, it will take the December solstice sun 36 years to precess through the Galactic equator.
Our solar system is part of a huge disc shaped collection of stars and planets called the Milky Way. We're located somewhere on the edge of the disc, slightly on top of the narrow disc. But very soon we'll be moving to the bottom of the disc. This change, from top to bottom, begins on December 21, 2012. |
