Measured timeline

📍 How it ended

Jupiter's moon Europa contains a saltwater ocean that may hold more than twice the water of all Earth's oceans combined. A new measurement indicates 29 kilometres of solid ice exists above this ocean, making it more difficult to reach than previously thought.

  • Source Integrity: Verified strictly against primary headline reporting under zero-hallucination protocols.

Jupiter's moon Europa contains a saltwater ocean that may hold more than twice the water of all Earth's oceans combined. However, new measurements indicate that 29 kilometers of solid ice separate the surface from this ocean, creating a barrier described as taller than three Mount Everests stacked end to end.

Coverage from Phys.org, Gizmodo, and Space Daily emphasizes that this hidden ocean is more difficult to reach than scientists previously thought. MSN and WorldAtlas highlight the moon's potential to provide clues about life beyond Earth, noting that such oceans can remain liquid far beyond the reach of sunlight due to gravitational warming.

Future focus remains on whether life can exist beneath the ice and how to navigate the significant distance between the moon's surface and its internal saltwater ocean.
