While anxiously waiting for data from the COSAC (Cometary Sampling and Composition Experiment) aboard the Philae lander, we turn to some of the information that has already been sent by the Rosetta\u2019s Rosina (Rosetta Orbiter Spectrometer for Ion and Neutral Analysis) instrument.  While sampling the comet\u2019s coma they have found carbon dioxide in nearly the same proportions as water. Rosina has the ability to measure the ratio of hydrogen to deuterium in water.  Deuterium is believed to have been created in the Big Bang 13.8 billion years ago.  Since deuterium accounts for approximately 0.0156% of all hydrogen found on earth, this data may shed light on the origin of our water.<\/p>\n\n\n\n

So far the following compounds have been detected by Rosina:<\/p>\n\n\n\n

Water, Carbon monoxide, Carbon dioxide, Ammonia, Methane, Methanol, Formaldehyde, Hydrogen sulfide, Hydrogen cyanide, Sulphur dioxide, Carbon disulfide and ethanol.<\/p>\n\n\n\n
