The "ultimate" building blocks of life have been found in interstellar…

The building blocks of life could have their beginnings in the tiny icy grains that make up the gas and dust found between the stars, and those icy grains could be the key to understanding how life can arise on planets. With help from students, researchers have discovered an important pair of prebiotic molecules in the … » 3/01/13 9:40am 3/01/13 9:40am

Haunting 3-minute music video tells the panspermia story better than

In Prometheus, we saw a mysterious alien seeding the Earth with DNA. This act of fertilizing a planet with life from space is called panspermia.

Our Alien Origins: 21 Panspermia Tales

Planet Earth might be home sweet home, but is it really humanity's birthplace? We explore science fiction stories where humans come from everywhere but Earth, be it by colonization, alien experiments, or good old-fashioned panspermia. » 2/01/09 2:00pm 2/01/09 2:00pm

More Proof that Aliens Could Be the Origin of Life

Did life on Earth originate when burning meteorites full of carbon molecules or single-celled organisms crashed to our planet and scattered their seeds? It's very possible, according to proponents of the theory of "panspermia." And now a group of researchers have proven that panspermia is technically possible, after a… » 9/26/08 11:16am 9/26/08 11:16am

Further Proof That Life May Have Originated In Space

We usually think of asteroid impacts as harbingers of mass extinction » 8/14/08 8:00am 8/14/08 8:00am, but they might be the reason life exists on our planet at all. It's possible for bacteria to hitch rides on rocks ejected by space impacts and move from planet to planet. We know that certain Earth bacteria are capable of surviving the hostile…
