    High levels of carbon dioxide and hydrogen on the sea surface of the Saturn Moon Enceladus can provide fuel for foreign life, experts say.

    Scientists suggest that living microbes could feed on this fuel – a chemical broth is called a "free lunch".

    They say, however, that its presence can also suggest "that there is hardly anyone to eat."

    This may mean microbes are not available in sufficiently high quantities to consume all available energy.

    WHAT WERE THE RESEARCHERS ABOUT ENCELADUS "OCEAN?"

    The study showed that the plumes are not chemically the same as the sea they break out and that the outbreak process itself changes its composition.

    The plum gives an "incomplete window" to the composition of the Enceladus marine and that the plum composition and sea composition can be very different.

    What they find is because gases separate, which means that some parts of the plume can explode while others remain.

    Using a computer simulation that presents the separation effects, they found "significant differences" between Enceladus plume and the chemicals in the sea.

    Previous interpretations they found, underestimating the presence of hydrogen, methane and carbon dioxide.

    Enceladus, Saturn's sixth largest moon, is an ocean world of about 310 miles (500 km) above.

    The saline subterranean sea is of interest to planetary scientists because of the similarity in pH, salinity and temperature to the Earth's oceans.

    In 2005, the Cassini spacecraft made the discovery that Enceladus is an active moon that hides a global sea of ​​liquid salt water beneath its crust.

    It also found that the jets of icy particles from that ocean, spun with water and simple organic chemicals, sputter into space continuously from it.

    The material shoots out at about 800 miles per hour (400 meters per second) and forms a plume that stretches hundreds of miles in space.

    Some of the material falls back on Enceladus, and some are released to form Saturn's large E-ring.

    The new study has shown that the plum is not chemically the same as the sea from which they break out and that the outbreak process itself changes their composition.

    The plum gives an "incomplete window" to the Enceladus subterranean ocean and that the plum composition and sea composition can be very different.

    What they find is because gases separate, which means that some parts of the plume can explode while others remain.

      Researchers suggest that living microbes could be fed on this fuel - a kind of chemical as a free lunch "or it could mean" that there is hardly any one to eat it. "This can provide a potential fuel for life and yet it may mean that microbes are not abundant enough to consume it.

    Using a computer simulation that responds to the separation effects, they found "significant differences" between Enceladus plume and chemicals in the ocean.

    It is better to find high gas concentrations than none at all, says lead researcher Dr. Lucas Fifer.

    "It seems unlikely that life would develop to consume this chemical free lunch if the gases were not abundant in the sea."

    The high carbon dioxide levels also mean a lower and more earthly pH level in Enceladu's sea than previous studies have shown. This fits well for any life, Fifer says.

    "Although there are exceptions, most life on earth works best in or consumes water of near neutral pH, so similar conditions on Enceladus can be encouraging," he said.

    "And they make it much easier to compare this strange marine activity to a more familiar environment."

    WHAT IS ENCELADUS AND CAN IT BE WORLD LIFE?

    ] Enceladus is Saturn's sixth largest moon, 313 miles wide (504 kilometers).

    It is an icy satellite with hydrothermal activity – a rare combination – with openings that spit water vapor and ice particles out of a global sea buried under the lunar crust of the moon.

    A handful of worlds are considered to have floating sea water during their frozen shells, but only Enceladus is spreading its ocean into space, where a spacecraft can try it.

    According to Nasa observations, the plum contains organic compounds, volatile gases, carbon dioxide, carbon monoxide, salts and silica.

    Microbes on our planet either create these compounds or use them for growth, which causes some to speculate that small organisms live in Enceladu's hidden seas.

    This means that while Enceladus may look "ineffective" as Saturn's other moons, it is an important candidate in our search for alien life.
