The official YouTube channel for NASA's Jet Propulsion Laboratory has released its stance on the much publicized December 21, 2012 Mayan doomsday scenario. (VIDEO BELOW)
In a nutshell - it's safe to make plans for December 22. NASA's Don Yeoman's gives insight that he say debunks some end of the world scenarios diehard Mayan Apocalypse observers believe.

Yeoman's first has issue with the Mayan calendar which is at the heart of the Apocalypse theory. Believers think that December 21, 2012 marks the end of the Mayan calendar and thus the end of the world.
"Their calendar does not end on December 21, 2012, it's just the end of a cycle, and the beginning of a new one," Yeomans said. "It's just like on December 31st our calendar comes to an end but a new calendar for the next year begins on January 1st."
But if the calendar happens to be right, here are some ways the world could NOT end, according to NASA.
One scenario has a giant planet, called Niburu, colliding or coming fatally close to Earth. Theorists say Niburu would be 4 times the size of our planet.
"So this enormous planet is supposed to be coming toward earth but if it were we would have seen it long ago and if it were invisible somehow we would have seen the effects of this planet on the neighboring planets," Yeomans explained.
Yeomans goes on to say that thousands of astronomers who scan the skies on a daily basis have not reported seeing anything like Niburu.
A conspiracy theory?
"Could you imagine thousands of astronomers who observe the skies on a nightly basis keeping the same secret from the public for several years?" He said.
This is probably the most likely end of the world scenario of the unlikely end of the world scenarios. Believers think the Sun will produce a storm too powerful for the Earth to withstand.
"The next Solar maximum, when you might expect enhanced solar activity will take place actually in May of 2013," Yeomans said. It's supposed to be a fairly mild solar activity maximum and there's no evidence that there's going to be any solar storms."

Some believe the Earth, and other planets, will align causing tidal effects that are going to be catastrophic.
"First of all there are no planetary alignments in December of 2012 and even if there were there are no tidal effects on the earth as a result,"Yeomans said.
Yeomans goes on to explain that only the moon and the sun could cause any effects on the Earth's tide.
Magnetic Poles Shift
Finally, believers suggest the Earth's axis will shift.
Yeomans explains that the Earth's rotation axis can't shift because of the orbit of the moon stabilizies it.
While the magnetic field does shift from time to time the last time it did was 740,000 years ago, there's no evidence that it's going to happen in December.
"Even if were to be shifting, it takes thousands of years to do so, and even if it did shift it's not going to cause a problem," he said.
"Extraordinary claims requires extraordinary evidence," Yeomans said. "Since the beginning of time there have literally been hundreds of thousands of predictions of the end of the world and we are still here."
