Welcome to Enceladus, one of Saturn’s moons.
Reminds me of Jupiter’s Europa, among other icy moons – a giant egg suspended in space, it’s frozen shell believed to hold a vast ocean heated by tidal forces, and with the possibility of the complex chemistry we call “life” swirling inside its amniotic depths.
Just waiting for when the sun enters old age and becomes a red giant in order to hatch. Beautiful!
