They range
from hydrothermal activity, acid fog from extinct volcanos, and even efflorescence, which is how salt deposits form in basements or on brick walls.
The paper from researchers with the Cassini mission, published in the journal Science, indicates hydrogen gas, which could potentially provide a chemical energy source for life, is pouring into the subsurface ocean of Enceladus
from hydrothermal activity on the seafloor.
The authors argue that it comes
from hydrothermal activity on the ocean floor, perhaps seafloor vents like those on Earth that spew H2 and support rich microbial life.
