Martian Methane May Be Created By Lifeforms

Posted by kdawson on from the little-green-bugs dept.

Following our recent discussions about the growing evidence pointing to possible life on Mars, reader skywatcher2501 writes with news of a study that has ruled out one possible explanation for the levels of methane seen on that planet — that it might be replenished by disintegrating meteors entering the atmosphere. So two theories remain: either the gas is created as a by-product of reactions between volcanic rock and water, or it is a by-product of a lifeform's metabolism.

    Methane concentrations peak in an area on the planet opposite the famous face on mars.

    Cows ruined their own planet before they came to earth millenia ago.
    Its this migration that the child's nursery rhyme is referencing in the line "the cow jumped over the moon".
    They're now doing the same to the earth.
