back to article Rosetta probe delivers jaw-to-the-floor find: Molecular oxygen

Rosetta has both delighted and upset astronomers after the probe sent back data that indicates the discovery of molecular oxygen on Comet 67P/Churyumov–Gerasimenko. The scientists are excited because the O2, detected in the thin cloud of stuff surrounding the comet, is going to give them a pile of new science; and upset …

    So the comets atmosphere is almost 4% oxygen? OK it's 4% of not a lot but bloody hell 'jaw dropping' is pretty apt.

      its only 20% on earth

        Even if the comet's atmosphere was 20% oxygen like Earth you couldn't breath there, since that atmosphere is a lot thinner on the comet than it is on Earth.

    I love the sound theories make...

    ...when they evaporate after someone heats them up with some actual measurements.

    Sort of a "whoompf" type sound. There may be a cloud of smoke.

    Unfortunatley it's usually closely followed by the sound theoriticians make when they learn that all their previous papers are wrong.

    Sort of a "sniffle" sound.

    There's no sound quite like it for cheering up the experimentalists!

    Beers all round I think.

      Like many real scientific advances, the cry is not 'eureka' but 'that's odd'.

      Maybe we have been assuming that life is only associated with planets, but there maybe other types that wake from deep freeze on comets.

        No - the sound is "BASTARD!!! I based my grant funding around the old science. Ooh. Maybe I can fudge the results?"

          Re: the sound is "BASTARD!!! I based my grant funding around the old science.

          Not really. If the funding has already been awarded, you just use it to do some science in the same area, but based on the new data.

          The "BASTARD!" would come in if you've just /submitted/ an application whose premise is ruined by the new data; because it now has 0% of getting funded (instead of e.g. 30%), and all the work writing it will have been for naught.

            But be sure trace the funding to see if it is directly or indirectly from one of the energy giants. Otherwise, how will you know what conclusions to draw?

      Plenty of examples in history of pure theory informing and guiding the experimentalists.

      You are aware that the theories about solar system formation work from the outside in? As in, they start assuming an homogenous mix of interstellar crap and get refined on observation accounting for the clumpy nature of realty.

      This is how science works. The sound you are listening for almost never happens as it is associated with the other major explanitory technique - "God did it. Stop asking questions."

      And one comet a solar system formation theory does not destroy.

    Ozone?

    Isn't Ozone more reactive than diatomic Oxygen (so even less likely to be found on the loose)?

    One vaguely wonders

    if comets have been spraying the Earth with ozone forever ? Yet (another) example of how the universe interacts.

      It's the giant space goat, I tell ya!

      Round up the marketeers, lawyers, bankers, middle management, and politicians, get them on the B-ark, pronto!

    Well, it was CO2 but the carbon converted to a smegging humongous diamond in the middle of the comet. What's left is O2. Now that would be jaw dropping,

    Comet .NE. planet

    Maybe planets are bigger than comets - duh.

    Maybe the energies involved go up as some power of the body's mass. Maybe a tiny comet would retain primordial oxygen, while heavier planets import sufficient kinetic energy with each mass contribution that they get hot enough to bake the oxygen, as well as melt rocks.

    I seem to recall that another famous comet, Shoemaker-Levy, achieved a fairly high temperature as it contributed its mass to the planet Jupiter. Any primordial oxygen accompanying Shoemaker-Levy would have done what? Hmmm...?

    This all appears to be perfectly obvious. Any primordial oxygen hovering around the planets?

    (PS. I've met Levy. Lovely chap. Autographed my copy of his book.)

    Euphemism award

    "We think this result is of interest beyond the cometary community" -- best euphemism we've seen for a few years, surely?

      Dear Little Mouse.

      Euphemism != understatement.

        Dear Supercillious Bleu

        It is an understatement for "This is an extremely interesting result for everybody."

        It is a euphemism for "FUCKING HELL, LOOK AT THIS!"

        Sorry you were not able to grasp that, did you need the joke alert?

          I am sorry to have mistaken you for Little Mouse.

          Mainly, I must apologise to Little Mouse, who probably would not confuse euphemism with understatement.

          Although my mistaken comment seems to have amused a few, likely including the Mouse.

          I am not sure that you know the meaning of 'supercilious', but you have a good line in blowing a fuse.

    or the INGSOC controlled EPA, NASA, NOAA cabal....see titled article at FauxScienceSlayer....

    Every atom and molecule in the Universe is under constant erosion from radiant energy and particle bombardment decay. The EPA demonized Nitrous Oxide in diesel exhaust combines with natural plant produced Isocene, C5H8 to produce the dreaded, GROUND LEVEL OZONE, producing fictitious 'asthma' symptoms. Ozone, O3 has a half life of thirty minutes, partly due to reactive nature and partly because it absorbs cancer causing UVA, a health benefit the WEAPONIZED EPA refuses to recognize. Ozone at 84 PPB in the atmosphere is NO problem. Ozone at one PPM has been used for domestic water treatment in Paris and thousand of other cities for over a century. Read
