"If you're watching this video, it means one thing: the world didn't end yesterday," begins a NASA video of Mayan calendar doomsday debunking. Obviously, the video was supposed to be released Dec. 22, 2012, but was published 11 days sooner instead. The documentary seems to be a spin-off of NASA's "Beyond 2012" web page, dedicated to those who have been asking about the Mayan calendar supposed doomsday predictions.

"The whole thing was a misconception from the very beginning," the NASA video continues.

The "Dec. 22 video" features scientists who have studied the Mayans and those who regularly study the space for Earth-threatening objects. They went on a Google+ Hangout session to discuss among themselves the ideas popularizing the 12/21/2012 end of the world predictions.

"If there were anything out there like a planet heading for Earth, says NASA astrobiologist David Morrison, it would already be one of the brightest objects in the sky. Everybody on Earth could see it. You don't need to ask the government. Just go out and look. It's not there."

The YouTube video description goes:

"The Mayan calendar explained! The world is safe from rogue planets, solar flares and other imagined calamities!"

"Watch this NOW to learn why NASA Science says you'll be here Dec. 22 to view it again!"
