Strong evidence exists that Jupiter’s moon Europa has a deep (60-100 km) liquid water ocean under its ~20 km thick icy crust. #OTD in 1999, @NASAJPL 's Galileo spacecraft took this 12-frame image of Europa from 94,000 km away. It was the highest resolution image to date.
NASA just detected water vapor on a moon of Jupiter — yet another clue that Europa's hidden ocean could hold alien life
If we discover alien life forms in the subsurface waters of Jupiter’s icy moon Europa, I wonder if we’d be compelled to call them “Europeans".
Confirmed: there's water vapor present above the icy surface of Jupiter's moon Europa. A research team led from @NASAGoddard made the detection — which supports the idea that below the ice, Europa has an ingredient necessary for life: liquid water. More:
Are you feeling a little salty today? The yellow color visible on the surface of Jupiter's moon Europa is actually sodium chloride — table salt. The discovery suggests that Europa’s ocean may resemble Earth's oceans more than previously thought. More:
Our upcoming mission to investigate the habitability of Jupiter's moon Europa now has a formal name: Europa Clipper:
