When did Jupiter's moon, #Europa, form its metallic core? Maybe recently... or not at all😮

A small moon like Europa may have formed as a cold mixture of hydrated rock and metal. While it is possible to accrete ice, there may already be enough hydrogen and oxygen in the rock to form the ocean!
Within the first 0.5–1.5 Gyr, Europa slowly warmed up until the onset of ocean formation. Hydrated rocks may release supercritical fluid, which would migrate to the moon's surface.
