Cooperation with AVA Biochem is part of comprehensive KIT activities for manufacture of chemical energy carriers as well as intermediates from biomass with emphasis on so - called hydrothermal methods i.e. reactions in water at increased temperatures.
Given that the tubules seem to be associated with fractures and water - cooled margins within the rocks, the researchers propose that hydrothermal activity — the local circulation of heated water, common after impacts — could have allowed microbial colonization of the glass from the surrounding environment.
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.
«If a new theory published last year is correct, then powerful hydrothermal activity could have been occurring since the formation of the moon, possibly as much as the age of the solar system,» he says, adding that which timescale they are working on — tens of millions or billions — could be determined with future research.
In an email interview with Newsweek, lead author Gaël Choblet, from the French National Center for Scientific Research, said that while he can not speculate on the presence of alien life on Enceladus, their timescale for hydrothermal activity does bolster the case that microbial life could emerge.
Cassini, which began its journey over two decades ago, facilitated the publication of more than 3,000 scientific papers with the data it collected and is responsible for several major discoveries, including liquid methane seas on Titan and evidence of hydrothermal activity on Enceladus.
On Earth, the most common way to form silica grains of this size is hydrothermal activity under a specific range of conditions; namely, when slightly alkaline and salty water that is super-saturated with silica undergoes a big drop in temperature.
Somewhere inside the icy body, there was hydrothermal activity — salty warm water interacting with rocks.
Additional unprocessed images gathered during Cassini's plunge are available online, along with hundreds of thousands collected by the probe during the more than 13 years it has spend studying Saturn and its moons — observations which resulted in the publication of more than 3,000 studies and such discoveries as liquid methane seas at Titan and hydrothermal activity on Enceladus.
We would not store in such regions of high hydrothermal and tectonic activity (having said that - some populations in Italy have CO2 seeping into their houses and gardens, but live with it, and buildings are constructed appropriately to prevent buildup of CO2 indoors; and in Africa even Lake Nyos has now been made safe by the construction of a gas lift siphon to prevent limnic buildup of CO2 in the lake bottom waters (the natural overturning of which caused the «burp» and subsequent deaths - although there were special, unique to that location, meteo.
Geologists now know that the Gakkel Ridge is an active zone of slow spreading tectonic plates with massive amounts of activity including explosive emissions of super carbonated magma that have blown the tops off dozens of undersea mountains, produced mineral / metal riches from extensive hydrothermal vents throughout the range and holds sea life around smoker chimneys with abundant hydrogen - sulfide based ecosystems.
