According to what I've read from NASA today, the story circulating around the internet these past few days about the earth will experience days of darkness in December this year was a hoax. This link http://huzlers.com/nasa-confirms-earth-will-experience-6-days-total-darkness-december-2014/ bore news about earth experiencing days of darkness from December 16-22.

Further scrutinizing the link they discovered that it has a disclaimer of satirical news in form. Sources from NASA added that almost every year news of the same form emerged like the earth and other heavenly bodies will align or morbid news such as the end the world. NASA claimed that there is no truth to that, they never release any statement to confirm such events.
