NASA Is Seriously Revving Up The Search For Alien Life

A few weeks ago, NASA chief scientist Ellen Stofan made news by saying, “I think we’re going to have strong indications of life beyond Earth within a decade, and I think we’re going to have definitive evidence within 20 to 30 years.” It was a bold statement, but NASA is now backing those words with action. » 4/22/15 9:00am 4/22/15 9:00am

This Short Video Explains Why You've Never Met An Alien

Given the extreme age of the Galaxy, extraterrestrial civilizations should have occupied every corner of it by now. Yet we see no signs of this. A short new video produced by New Scientist beautifully explains why the Fermi Paradox is a very real scientific problem and why it should be taken more seriously. » 12/16/14 10:40am 12/16/14 10:40am

Have Humans Already Conquered The Threat Of Extinction?

The Great Filter theory suggests that all advanced civilizations eventually destroy themselves before acquiring the capacity to colonize space — a notion that could explain why we've never been visited by aliens.
