# Europa’s Hidden Ocean May Be Even Harder to Reach Than We Thought

## Executive Summary
New measurements suggest a massive ice barrier may hinder access to Jupiter's moon Europa and its potentially life-sustaining saltwater ocean.

## Intelligence Brief
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 ice layer makes the hidden ocean more difficult to reach than scientists previously thought. MSN and WorldAtlas highlight the moon's potential for life beyond Earth and the role of icy moons in expanding the concept of habitable zones beyond a narrow ring around a star.


Future focus remains on whether life exists beneath the ice and the challenges of penetrating the frozen surface, which is kept liquid by gravitational warming despite being far from life-sustaining sunlight.

## Verified Facts & Key Claims
### How thick is the ice layer above Europa's ocean?
New measurements place the solid ice barrier at 29 kilometers thick.

### How much water is estimated to be in Europa's ocean?
It may contain more than twice the water of all Earth's oceans combined.

### Why is the ocean liquid if it is far from sunlight?
According to Space Daily, these vast oceans may remain liquid due to constant gravitational warming.
