That’s because there is less energy available for microbes within the crust than within the ocean. Using a model, the researchers suggest that Europa's water partially froze into ice after the impact happened, creating "pockets" of salty or briny water in the crust. In the visible part of a spectrum there are distinct features called "color centers" that appear when irradiated by very energetic electrons. You can clearly see the cracks on Europa's icy surface in this colorized photo from NASA's Galileo ... [+] spacecraft. It is also the sixth-largest moon in the Solar System. Now a new study, published in Science Advances, shows it may well be normal table salt (sodium chloride)—just like on Earth. Artist's concept image by NASA / JPL. It would be super-useful to have a spacecraft to observe Europa up close, to resolve this debate about whether the water plumes are indicative of a life-friendly environment. © 2020 Forbes Media LLC.

Streaks of reddish-brown color highlight cracks in Europa’s outer layer of ice. Europa is also criss-crossed with long troughs, folds and ridges, potentially made of icebergs floating around in melt-water or slush. NASA is building a spacecraft called Europa Clipper that could give us more insight into how that Jupiter moon is spewing so much water into space. That means they really are likely to come from Europa's interior. Europa’s vast and unfathomably deep ocean is widely considered the most promising place to look for life beyond Earth. Astrobiologists— scientists who study the origin, evolution and future of life in the universe — believe Europa has abundant water and the right chemical elements, but an energy source on Europa has been difficult to confirm. More precisely, if the water comes from zones of water inside the ice shell, the water would likely be less habitable than if the source was from the vast ocean below. I began full-time freelancing about this topic in September 2012, after working as a business reporter, copy editor and web reporter at various publications. The type of life that might inhabit Europa likely would not be powered by photosynthesis – but by chemical reactions. On Earth, hydrothermal vents are thought to be a source of life, such as bacteria.
