Space rock contains organic molecular feast Scientists believe the Murchison meteorite could have originated before the Sun was formed, 4.65 billion years ago. The researchers say it probably passed through primordial clouds in the early Solar System, picking up organic chemicals.
A study using high resolution analytical tools including spectroscopy allowed the team to identify 14,000 different compounds including 70 amino acids in a sample of the meteorite...
Dr Schmitt-Kopplin hopes the findings might contribute to the debate over how life on Earth originated.

You ain't gonna get in that tub, are you? It's the water that it wants, Jordy. Don't you know that? You get in that water, Jordy, you might as well sign your death warrant.

I came here expecting a post about Hawkwind. Now I'm disappointed.

"There are certain people who do not come to full flower until they are well over fifty five billion. Among these are all males named Murchison..."

the Murchison meteorite
It's a good name; they can call the resulting ancient space-based plague which destroys all life on earth when they crack this thing open and the black oil spills out and infects everyone, the Murchison Condition.
It has a nice ring to it. It'll look good on the tattered newspapers drifting around lifeless cities. (if post-apocalyptic sci-fi has taught us nothing else, it's that there will always be newspapers scattered around with the final headline for humanity)
Joking aside, vastly old organic chemicals from space are freakin' cool!

Well, you remember that total eclipse of the sun a few weeks ago...

"The new EP from Brit prog-rock group Hawkwind is track after track of an organic molecular feast, as though it passed through primordial clouds in the early Solar System, and airplay of the first single quickly shot up the college radio charts."

It seems truly amazing that a rock old enough to have passed through the cloud of stuff that would eventually become the solar system would hang around in the same general area - galactically speaking, at least - for so incredibly long until ultimately smacking back into a concentrated lump of that cloud, billions of years later. It's just staggering to think of it looping around - I'm assuming it must have just had a really long orbit period around this cloud, right? - who knows how many times, and then finally, on one pass - whomp! Right into Australia! It just seems so improbable, both that it didn't end up flying off elsewhere in the universe and that it would strike the Earth - and on land, even!
When I come across stuff like this, it makes me wish my grandmother were still alive so I could talk about it with her.

Maybe it is merely one of many similar objects.

Space rock is also better consumed after an organic molecular feast.

Burhanistan, I look at that clip now and I have to wonder, "How high was Stephen King when he did that?"

nickmark, your grandmother wrote books about meteor craters? Mine doesn't even knit.

I'm fascinated with the idea of panspermia, that life on Earth actually originated elsewhere, whether accidental or designed. Which made me do a double-take on this quote:
"The researchers say it probably passed through primordial clouds in the early Solar System, picking up organic chemicals."
Organic, you say? Does this mean chemicals usually found in plants or animals? As in, alive? What else could "organic" mean in this sentence? And also, can anyone say how big of a leap is it to paint a panspermia picture with a rock like this as evidence?

Containing carbon. This allows for the existence of larger and more complicated molecules that make life possible.

I am not an organic chemist ... How is it that these amino acids are stable enough to survive 5 billion years of cosmic rays and the friction heating of earth entry?

im not an organic chemist either, but the answer is definitely Ghostbusters II

In body text-replace sun with earth. Very nice find too.
