Could humans live on Mars? 'Absolutely,' a NASA expert says
This suggests there could be oxygen "comparable to the concentrations in Earth's oceans today. Stamenkovic said: "Thus, in principle, Mars could offer a wide range of near-surface environments with enough dissolved oxygen for aerobic respiration like that seen in diverse groups of terrestrial microorganisms. Searching alien life is something which a growing number of groups believe NASA should be doing more regularly.
This story originally appeared in The Sun. A liquid water lake found on Mars Researchers believe they have uncovered a persistent body of water beneath the south polar ice cap of Mars. There is also plenty of radiation around Jupiter to potentially start chemical reactions strong enough to also very quickly destroy any organic compound formed. While the seemingly obvious mission would be to orbit Europa for a few years, any spacecraft doing this would be exposed to life-shortening radiation from Jupiter. Instead, Europa clipper will orbit Jupiter, dipping in and out of its radiation belt.
It will carry out at least 45 close flybys of Europa over three and a half years. A mixture of cameras and spectrometers will examine the moon and its tenuous atmosphere. Cassini arrived in the Saturn system in and conducted 23 flybys of Enceladus and of Titan before the mission ended in September Enceladus, which orbits Saturn, is believed to have hydrothermal vents, like those which may have kick-started life on Earth.

So Cassini went closer, and then closer again. As with Europa, it is assumed that friction caused by gravitational forces from Saturn means Enceladus heats up from the inside out. This third flyby also collected evidence of a plume of material jetting out of the stripes. The ion and neutral mass spectrometer on board Cassini detected organic molecules in the plumes, both in the gases and in the particles within it, up to the limit of the instrument. Other exciting findings in the plume data were the excess of hydrogen and the detection of tiny grains of nanosilica, which can only form in very hot water.
Hydrothermal vents form at locations where seawater meets magma. Water goes down cracks into the core, is heated and then comes back out again at force. On Earth, hydrothermal vents are teeming with organisms that are not seen anywhere else.

Hydrothermal vents on Enceladus, and other planetary bodies, are therefore potential sites for life. Enceladus, like Europa, is believed to have a global ocean under its icy surface. A study of 10 years of Cassini data, looking at the vibration of the moon, found that the core and the crust are not fixed together.
The data collected by Cassini shows that Enceladus has the three ingredients needed to support life, but no evidence that life is actually present has yet been found.
Aliens could be hiding on Mars living in briny water under planet’s surface, new study says
Voyager 1 visited the region in In , astronomers used telescopes to discover that this moon had a thick atmosphere containing methane. Data collected by Voyager spacecraft then showed that it was mostly nitrogen, a few percent methane and smaller amounts of hydrocarbons such as ethane, propane and acetylene. The instruments on board Cassini — and its Huygens probe, which landed on Titan in January — were not able to identify these ions, just confirm that they exist. These molecules are formed when the nitrogen and methane on the outside of the atmosphere are broken down by ultraviolet light and radiation, and then recombine in all kinds of ways.
Titan is also thought to have a liquid water ocean beneath its icy surface. Again, as is suspected for the other moons with subsurface oceans, life could exist down there. Titan has lakes across its poles. It is the only place other than Earth known to have a liquid on its surface. The Cassini mission determined that they are full of supercold ethane and methane, which are gases on Earth.

On Titan, these liquid hydrocarbons carve river valleys, form clouds and fall as rain. But could they also act as the solvent needed to support life? It might just be a different set of molecules that work better at those temperatures with that solvent. The idea is that this sort of assembly is called an azotosome, an analogue to the liposome in conventional biological chemistry.
