Most complex extraterrestrial molecule

    What is the most complex extraterrestrial molecule yet discovered?

    By 'complex extraterrestrial molecule', I believe the you are referring to an organic molecule.

    My data is limited, but I believe that the most 'complex' molecule discovered is Glycine.

    However, the dicovery of Benzene is certainly an impressive discovery.

    The 'heaviest' organic molecule discovered is (HC11N).

    Streptococcus Mitis (A Whole Microbe!)

    How about some common bacteria living on the Earth's Moon?

    Streptococcus Mitis, (apparently, originally, from Earth);

    It'd be something if terrestrial bacteria managed to survive and mutate into heterotrophs on the moon. The whole lunar surface might change color.

    Jenab,

    Given the right strain, it might well ferment into cheese! :biggrin:

    wouldn't a binary or multiple star system or tight cluster consisting only of neutron stars technically be considered a molecule? and would it be complex based on transfinite numbers of neutrons- or simple?

    Thats wonderful.

    The success of A. does not necessarily ensure the failure of B.

    Nonsensical s**t is pretty boring, isn't it?

    no, i wouldn't call it a molecule anymore than a neutron beam is one

    you need all the parts, nuclei, electrons and the lot

    is the solar system an atom? nah

    I don't know how you'd go about determining which was the 'most complex', but the Murchison meteorite certainly contains (contained? no, pieces are still around) a wide variety of complex organic molecules, and fullerenes.

    I think Dogon is referring to the Streptococcus mitis which hitched a ride on Surveyor 3. Doesn't really count as 'extraterrestrial', since it came from Earth :smile:

    Yep, it was a hitch-hiker (from Earth) alright.

    But, if it LIVES in space, BREATHES in space and REPRODUCES in space (for a period of YEARS).
    Then;

    I have 100% confidence that Streptococcus mitis is EXTRATERRESTRIAL in origin (ie. It DID NOT originate on Earth, but has adapted to Earth-like conditions, whilst retaining the ability for space travel).

    My guess would be that the "hitch-hiker" colonised Earth through Panspermia...
