... source is converted to thermal energy in the melting heads on the probe, but to melt through the thick ice of Enceladus with the ‘glacial’ velocity of 1 m/hour, an estimated 5 kW must be produced by the power source on-board the lander. As the...
...releases the salts, making the surrounding water heavier, causing it to sink. The opposite happens in regions of melt. If Enceladus had churning oceans akin to those on Earth, a pole-to-equator circulation would influence the distribution of heat and...
... to how probable we believe different hypotheses are to begin with," he said. "For example, if we deem the probability of life in Enceladus to be extremely low, then such alternative abiotic mechanisms become much more likely, even if they are very...
... to fill the gap before missions such as JUICE get underway. “This finding shows that detections of molecules at Enceladus are possible using ground-based facilities. However, to understand the complex chemistry in these subsurface oceans, we will...
...new finding is therefore an independent line of evidence supporting the theory of hydrothermal activity taking place in the ocean of Enceladus. This graphic illustrates how Cassini scientists think water interacts with rock at the bottom of the ocean...
...1980s. Scientists had long suspected that the ocean below Enceladus's icy exterior could harbour the ingredients for life, but... say that chemical reactions with iron deep in Enceladus’ core is creating molecular hydrogen (H2). Then hydrothermal...
