Discussion Overview

The discussion centers around the question of the most complex extraterrestrial molecule discovered, exploring various organic molecules found in space, as well as the implications of terrestrial microbes potentially existing beyond Earth.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants mention that over 130 molecules have been identified in interstellar space, including sugars, ethanol, and amino acids, with glycine being suggested as a complex molecule.
  • Others propose that benzene is also a significant discovery in the context of extraterrestrial molecules.
  • One participant claims that the heaviest organic molecule discovered is (HC11N).
  • There are references to terrestrial bacteria, such as Streptococcus mitis, potentially surviving on the Moon, raising questions about their classification as extraterrestrial.
  • Another participant discusses Mars meteorites containing fossilized bacteria, suggesting they represent extraterrestrial life.
  • Some participants debate whether a binary or multiple star system could be considered a molecule, questioning the definitions of complexity in this context.
  • There are humorous remarks about the implications of bacteria surviving on the Moon and the potential for them to change the lunar surface.
  • One participant expresses skepticism about classifying Streptococcus mitis as extraterrestrial since it originated from Earth.
  • Another participant argues that if a microbe lives and reproduces in space, it could be considered extraterrestrial, regardless of its origin.

Areas of Agreement / Disagreement

Participants express a variety of views on what constitutes the most complex extraterrestrial molecule, with no consensus reached. There is also disagreement regarding the classification of certain microbes as extraterrestrial.

Contextual Notes

Discussions include assumptions about the definitions of complexity and extraterrestrial life, as well as the implications of microbial survival in space, which remain unresolved.

What is the most complex extraterrestrial molecule yet discovered?
 
Astronomy news on Phys.org
Distant Dust...

Over 130 molecules have been identified in interstellar space so far, including sugars and ethanol. But amino acids are a particularly important find because they link up to form proteins, the molecules that run, and to a large extent make up our cells



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?

Mars Meteorites' Fossilised Bacteria

Or, how about the 50 or so Mars' meteorites, with fossilised bacteria?

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 http://science.nasa.gov/headlines/y2001/ast20dec_1.htm

I think Dogon is referring to the Streptococcus mitis which http://science.nasa.gov/newhome/headlines/ast01sep98_1.htm . 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...
