The Water in Our Bodies Makes Us All Part Alien, Sort of

“A new study published today (Sept. 25) in the journal Science suggests that between 10 to 30 percent of the Earth’s water is older than the sun, and likely hails from comets born outside our solar system. That means that the human body, which is 60 percent water, contains a significant percentage of extraterrestrial aqua; in that sense, we are all part alien.”  – Douglas Main, Newsweek

And if it’s true of us, it’s probably true of others. Life elsewhere may take similar forms because water may form its basis, as it does ours.

Oceans of Water Beneath Our Reach

A study published yesterday in the journal Science suggests oceans of water are locked in rock about 400 miles below Earth’s surface. It’s not liquid, ice or vapor, but rather hydrogen and oxygen embedded in the molecular structure of mineral rock. Researchers think it may help explain some things about how the planet formed, and how oceans gathered on the planet’s surface, which is great. But for many observers the first question is, how do we get at it? And the answer is a flat no, we don’t get anywhere near this stuff, much less turn it into a usable form, because it’s far too deep in the mantle. It’s 400 miles down, and the deepest humans have ever drilled is less than 10 miles.
