Vast hidden ocean beneath Earth’s mantle? Scientists stunned by new discovery - Futura, le média qui explore le monde

The ocean beneath Saturn's moon Enceladus lies under kilometers of ice, but some of its contents do reach the surface. Jets near the south pole spray out water vapor and icy particles, offering a way to investigate the hidden ocean without drilling down to it.

The Ross Ice Shelf is Antarctica’s largest floating ice platform, covering an area about the size of France. In 2017, a research team drilled a borehole through 320 meters of central shelf ice. They lowered instruments 420 meters into the dark water column below. Between 2018 and 2022, these sensors recorded continuous ocean data underneath the floating ice sheet.

Powerful dishes isolate a distant planetary signal A research team led by Kevin N. Ortiz Ceballos analyzed four observing sessions conducted between February 2025 and May 2026. They used the 64-dish MeerKAT radio telescope in South Africa to scan the young Beta Pictoris star system.
