Good old YouTube.
This seems to be the start of it, a lengthy
in-depth' presentation on the CourageousNerdz Channel where they use genuine interviews with astronomers/scientists/NASA personnel and then misinterpret it to the max.

Then u get spin offs like 'NASA KNOWS COMET ISON IS A SPACECRAFT' and
'
Nibiru ALERT 2013 2014 genuine need to panic MUST WATCH comet Ison Nibiru latest 2013 data'.
People believe this rubbish though!!
But how do the perpetrators continue to justify their mad claims when it all comes to naught?
Surely some of them are just pranksters because to predict the 'End of the World' sometime next month is a invitation to failure and ridicule.
Oh, and it turns out that the remake of the 'Day The Earth Stood Still' is actually a veiled NASA expose of the 'Truth' about ISON and comets generally. So, that's cool, eh? Just need to rent this movie to bring myself up to speed on NASA's secrets.
