beecee Posted March 23, 2022 Share Posted March 23, 2022 Does life exist elsewhere within our Solar system? While as yet we have no conclusive evidence of life existing anywhere else,other then Earth, including in our Solar system, we do have possible havens for life, although anything beyond the most microbial and basic of life would be unlikely. Some possible niches for life maybe the following places..... Titan, Saturn's largest moon. https://www.smithsonianmag.com/science-nature/where-solar-system-are-we-most-likely-find-life-180949994/#:~:text=In terms of life, Titan,amounts of methane and oxygen. In terms of life, Titan—the largest moon of Saturn—has one thing going for it that none of the other destinations do: a thick, chemically active atmosphere. The moon's atmosphere is denser than Earth's, and the upper levels are mostly composed of nitrogen, with small amounts of methane and oxygen. This is encouraging, as life (at least on Earth) requires an atmosphere for protection from radiation and for the circulation of organic compounds. Europa: Europa, a moon of Jupiter, is an ice covered world where life could possibly emerge...It would likely be beneath the icy crust, due to the extremes of radiation from Jupiter, but it does likely have sub-surface water and chemical activity. Enceladus: This is another smaller moon of Saturn, but has been observed to have powerful long plumes of water vapour erupting from the surface, as detected by the Cassini craft, along with many other more complex organics. Water has also been found on Ganymede the largest Jovian moon, and the largest in the solar system, as well as Callisto, Jupiter's other large moon. So what are the chances that some basic life has arisen elsewhere in our solar system? and when will we be sure of such possibilities. Some scientists seem to predict within the next decade or two. Such findings, when they occur, may either give us a better idea of the process of Abiogenesis, (the only scientific theory for the emergence of life) or possibly indicate a support for another varient of Abiogenesis, namely Panspermia. I just hope that such evidence is forthcoming before I kick the bucket. 1 Link to comment Share on other sites More sharing options...
