It is possible, but it could also be volcanic activity. Here is ESA's article about the discovery. <div class="Discussion_UserSignature"> </div>

odysseus145 - OK, that was from March, and the article indicated that in the weeks to follow they would try to determine if volcanic activity would cause the 10 parts in a billion trace presence of methane (CH4). <br /><br />Is there an update?<br /><br />Methane is more stable than more complex biological compounds, which is why earth has vast methane deposits from ages ago.,<br /><br />Volcanic activity is not necessary. It could simply be seepage from underground deposits of methane.<br /><br />Chemical evolutionists propose early earth had methane BEFORE life, and that life chemically evolved from this gas plus ammonia (NH3) and water (H2O)- however there is no reasonable chemical pathway that has been demonstrated experimentally to produce life, not to mention simpler molecules like statistical proteins, in this way.<br /><br />And geological deposits do not confirm large amounts of methane on early earth.<br /><br />That being said, methane can be caused by various other methods- which is why methane is located on other planets and moons. <br /><br />It simply involves combining Hydrogen (H2) and carbon (C). These elements are more likely to combine to form CO2 and H2O in the presence of oxygen (O2). <br /><br />Oxygen is the most abundant element in earth's crust.<br />
