    Men heeft ontdekt dat op Enceladus vermoedelijk alle elementen aanwezig zijn om leven mogelijk te maken.

    The paper from researchers with the Cassini mission, published in the journal Science, indicates hydrogen gas, which could potentially provide a chemical energy source for life, is pouring into the subsurface ocean of Enceladus from hydrothermal activity on the seafloor.

    The presence of ample hydrogen in the moon's ocean means that microbes – if any exist there – could use it to obtain energy by combining the hydrogen with carbon dioxide dissolved in the water. This chemical reaction, known as "methanogenesis" because it produces methane as a byproduct, is at the root of the tree of life on Earth, and could even have been critical to the origin of life on our planet.

    Life as we know it requires three primary ingredients: liquid water; a source of energy for metabolism; and the right chemical ingredients, primarily carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. With this finding, Cassini has shown that Enceladus – a small, icy moon a billion miles farther from the sun than Earth – has nearly all of these ingredients for habitability. Cassini has not yet shown phosphorus and sulfur are present in the ocean, but scientists suspect them to be, since the rocky core of Enceladus is thought to be chemically similar to meteorites that contain the two elements.

    Nog even als aanvulling. De grote hoeveelheid waterstof die men ontdekte in de geiserfonteinen doet vermoeden dat er waarschijnlijk niets is dat deze waterstof consumeert. Kans op leven zou groter zijn op de Europa maan.

    As to which ocean offers the best prospects for life, NASA astrobiologist Voytek said she would still bet on Europa. That Cassini found such high concentrations of hydrogen in the plumes of Enceladus may well mean that there is nothing in the moon's oceans consuming it. There is also evidence that Enceladus could be considerably younger than the moons of Jupiter, giving life less time to form there. "My money for the moment is still on Europa, but it could be on any of these moons," she said. "It would be great if life were on all of them.

    Bij mij staat hij op plaats 4 voorlopig. Zou wel eens in mijn top 3 kunnen komen na deze nieuwe ontwikkelingen...

    Er is geen buitenaardse leven.
    Het heelal is zo groot, dus in theorie zou er daar boven een file moeten zijn van buitenaardse wezens die rond kruisen door het heelal...

    Je gelooft wat je wil natuurlijk maar de kans dat er geen buitenaards leven is is kleiner dan de kans dat wij uberhaut bestaan. Heel erg miniem dus.

    Het grootste probleem is dat alles heel ver uit elkaar ligt.

    Maar wat als ze buitenaards leven ontdekken? Wat dan? We geraken daar dan toch NOOIT.

    LOL, Nieuwsblad haalt die info van "Secure Team" op YouTube, waar normaal gesproken geen kat iets van gelooft, maar ineens doen ze (Nieuwsblad) dat dan wel
    Trouwens .. "En het bewijs dat ze hierover verzamelen, lijkt hen te vertellen dat het zelfs geen planeet is ". Wat nu ?
    Oh en Lak noem de maan gewoon "Death Star" dat zal er al dichter op lijken.

    Er is daar al eens een kansberekening over gedaan en volgens de rekenkundigen die die kansberekening gemaakt hebben is die kans zo goed als 0,0. Ik bedoel de kans dat er geen buitenaards leven is. De mens en zijn idiote hoogmoedigheid is de enige echte reden dat mensen zoiets niet mogelijk achten.
