Asteroids make life's raw materials - environment - 04 May 2011 - New Scientist: "WERE asteroids the factories that created life's building blocks? For the first time, rocks from an asteroid have been shown to power the synthesis of life's essential chemicals.
The asteroid in question fell to Earth on 28 September 1969, landing on the outskirts of the village of Murchison in Victoria, Australia. Tests showed it was laced with amino acids and some of the chemicals found in our genetic material.
The discovery suggested that space was not the chemically sterile place it was once thought to be, and that organic chemistry was widespread. It hinted that the molecules life needed to get started could have been produced in space, before dropping to Earth."
