How comets smell like?


    Чем пахнут кометы?

    Studies of comets are not standing still. Perfect example – the story of the descent of preparing the spacecraft “Rosetta” on the surface of one of these blocks, wearing a cosmic void. These celestial bodies have long and lively interest of scientists from different fields, and the reasons for that are many (one of them, of course – the panspermia hypothesis).

    But let complex scientific matter to the competent people in them and think about the simple but interesting things. Example of what smells like a comet!

    This is quite a strange question we can answer today thanks to the latest scientific data from two mass spectrometers Rosetta, “sniff” celestial body 67P (also known as the comet Churyumov-Gerasimenko.)

    Technically, devices “Rosetta” not caught the smell, and the chemical composition of comets. And thanks to the knowledge of the chemical composition, we can imagine the smell of rough cometary material. So, what is the comet Churyumov-Gerasimenko? This:

    • Water (H2O)
    • Carbon Monoxide (CO)
    • Carbon Dioxide (CO2)
    • Ammonia (NH3)
    • Methane (CH4)
    • Methanol (CH3OH)
    • Formaldehyde (CH2O)
    • Hydrogen sulfide (H2S)
    • Hydrogen cyanide (HCN)
    • Sulfur dioxide (SO2)
    • Carbon disulfide (CS2)

    This powerful chemical cocktail, if he were on earth, would have smelled, to put it mildly, disgusting. According to experts from the European Space Agency, “if you smelled a comet, then you about this immediately be spared.”

    If you are not satisfied so suddenly faded description and you want the juicy details, please – Catherine Altwegg, leading researcher of the “Rosetta” comet has undertaken to describe the smell in the details:

    “Fragrance at 67P / CG is very strong. It is possible to catch the acrid smell of rotten eggs, the stench of the stables and sharp and suffocating smell of formaldehyde. All this spiced bouquet nauseous and bitter almond smell tsianvodoroda. Add to this the notes of alcohol in the form of methanol, acetic aroma of sulfur dioxide and a touch of sweet flavor of carbon disulphide and you will feel the same “comet perfume.”

    Readily believe, but is unlikely to be able to check (to the great happiness.)
