What is life, according to NASA?

We often think of aliens as space monsters or little green men with laser guns, but what might alien life actually be like?

Here we take a look at NASA's definition of life, and see how it's being used in the exploration of the cosmos, as well as in the chemistry lab as researchers search for the possible pathway from simple chemistry to living cells.

Biochemist Seven Benner's book is the most comprehensive look at NASA's definition as it applies to space exploration and life origin's chemistry. I highly recommend it!

DISSENTING VIEWS ON NASA'S DEFINITION OF LIFE
Scientists and philosophers are a wild bunch of free-thinkers, as such, not everyone jumped on-board when NASA put forth their definition.

Jon, if you keep this up you'll be the toast of NASA in no time.

As an Ambassador for the Okenite Crystal Community, I'd like to object to this video!

The efficacy of making the sophisticated issue simpler is the matter of competence and expertises in journalism

[dkpsyhog]

Well if we found strange living black goo on an alien world I think it’d hold a few people captive in a crashed spaceship and drown all who dare approach.
That’s a terrible reference, wasn’t it? No one will get it...

[PalaeoJoe]

Really there are very few little Green men in actual works of Sci-Fi.

5:09 that satellite looks like a beer can with wings.

The NASA definition: It’s life, Jim as we know it.

[aniksamiurrahman]

The best video I've seen on YouTube.

[jivejunior]

Can you make a video deriding the horribly unrealistic portrayals of aliens in science fiction? The fact that aliens are often made to be humanoid gray beings with cat eyes just rustles my jimmies!

We need to know what's alive so we know what to purge.
