Spectrum of Orion

I find this to be very cool - click the pic for big. This picture represents spectral analysis of light from the Orion Nebula.  This pic was obtained by the European Space Agency's Herschel Space Laboratory. What it shows is groundshaking: All the ingredients needed for life are floating in the vast dust clouds of Orion, including water. Now, we already knew this, but this is the first time we've been able to see so clearly that this is true, and is most likely true in all directions of space.

Meaning, to me, it's just a matter of time before we discover life off earth, and its also possible - maybe probable - that life on Earth came from space. I don't know if we can ever know for sure though, as no one was around back then to confirm. 

We might find there's been multiple origins of life on Earth - under the sea, from space, from the atmosphere, etc. Life is always grander than anticipated.
