In fact it is the third most abundant molecule in the regions which were studied source . NASA lab experiment suggests life can exist in deep space. Researchers create chemical compounds in laboratory simulation of interstellar conditions. Some of the components have properties relevant to the origin of life, including the ability to self- assemble into vesicular structures source . See also .
Satellite finds organic molecules in interstellar dust from far beyond solar system.
There is evidence that there is terrestrial-type material orbiting most of the stars in the solar neighbourhood. So, the implication, if this result holds up, is that there are Earth-like bodies in orbit around most of the stars in our galaxy source . Say they may be more common than thought. Total number of known exoplanets now 53 source . New calculations suggest exoplanets could be common source .
