The galactic alignment occurs once every 26,000 years but Earth crosses the Milky Way's galactic plane (also called the galactic equator) twice a year, every year.

This is actually two separate questions. Be sure you read both answers. "What will happen when the Earth passes through the galactic equator?" The Sun orbits the center of the Milky Way galaxy in about 200-250 million years. However, the Sun's movement is not a simple ellipse; it's more complicated than that and it bobs up and down as it moves. It oscillates around 2.7 times for every orbit, and some scientists think that the periods when it is moving through the denser regions of the galactic plane coincide with mass extinction events on Earth. "What does 2012 have to do with this?" Absolutely nothing. The 2012 scare is a hoax/myth/scam. The Sun is not currently particularly close to the galactic equator and it won't be significantly closer in 2012.

You will need Galactic key and this how to get Galactic key you will need to talk to a Galactic team mate by the Galactic HQ.
