The events that led to the origins of life on Earth are a mystery.  Where did our primordial ooze-like ancestors get their start?  Deep-sea ocean vents?  A big life-factory in the sky?  Some spontaneously formed microbial version of the Octomom?  The cold, harsh cradle of space?  Thanks to evidence retrieved by the NASA spacecraft Stardust from the comet Wild 2, that last option is beginning to gain some traction.    

So should we all start changing our nametags from "Earthling" to "Spaceling"?  And what could this mean for other potential lifeforms out there in the abyss?  Watch to find out.
