An ocean under the ice

Sunlit cracked ice over deep blue water — the roof of an ocean nobody can see. Moons like Europa and Enceladus hide whole seas under shells like this, warmed from below, dark for billions of years. The dark-oxygen discovery matters here too: if oxygen can be made in darkness on our own seafloor, the hidden oceans out there may not be as lifeless as we assumed. The carousel this slide closed began with nodules in the black and ended, as these questions tend to, with another world.
