Is there a person in the world that hasn't seen sci-fi classic "E.T.: The Extra-Terrestrial?" Steven Spielberg touched hearts with this story of friendship between an alien and humans.
SETI stands for "search for extra terrestrial intelligence." Just think about the movie Contact with Jody Foster.
And while for more than a decade you've been able to offer your computer to help SETI at Home, the organization will soon offer to open its system up to people who think they have better ideas as to how to look.
Put another way, you've always been allowed to help SETI find the answer, now you can help them ask the question.
