We realize that this is a radical conclusion. If we're right, we think we are looking at another environment in the solar system where we have liquid water and the potential for living organisms.
As far as I'm concerned, we just hit the ball out of the park. This is the Holy Grail of modern-day planetary exploration, evidence of liquid water somewhere else in the solar system.
However, if we are right, we have significantly broadened the diversity of solar system environments where we might possibly have conditions suitable for living organisms.
