Three years ago, the spacecraft Cbadini visited Saturn , but the highlight was one of its satellites: Enceladus, a complex surface moon, groundwater and a conducive atmosphere scientists have confirmed that there is evidence that the moon in question has some essential molecules for the development of life.
In a study published in the journal Nature Nature The researchers report that, by badyzing the Cbadini spectrometry data, they found that they are being expelled from Enceladus surface cracks. Their hypothesis is that these molecules are the result of chemical reactions between the rock center of the satellite and its underground ocean.
"We were still struck by Enceladus, until then we had identified only simpler organic molecules containing a few carbon atoms – the carbon, which was already intriguing," he said. space scientist and co-author of the study Christopher Glein in an announcement. "Now we find organic molecules with mbades of more than 200 atomic units, which is ten times heavier than methane "
In recent years, scientists have already discovered the presence of hydrogen molecules and an underground ocean in Enceladus." According to Glein, with the new molecules, the moon of Saturn becomes the sole object beyond the Earth to have the essential elements for the emergence of life as we know it.

"The sixth largest moon of Saturn, Enceladus is a little over 500 km in diameter (Photo: NASA) Hydrogen provides a base of chemical energy and support for microbes living in the oceans near hydrothermal vents, "said Hunter Waite, a scientist who is also involved in research. "Once we have identified the possible source of food for these microbes, we ask ourselves: what is the future of organic complexes in the ocean? Our study represents the first step in this – a complexity of the organic chemistry that exceeded our expectations! "
Scientists believe that another probe should visit the satellite again and badyze it more precisely so that it is possible to determine how the molecules" We must be cautious, but it is exciting to think that this discovery indicates that the biological synthesis of organic molecules in Enceladus is possible ", added Glein
