Europa's hidden ocean may be deeper than all of Earth's combined
In short: While Europa is a primary target for finding extraterrestrial life, it presents some of the most daunting colonization challenges in our solar system. This video explores why this icy moon is both a biological goldmine and a logistical nightmare.
Europa qualifies as a top candidate for life because it meets three essential criteria: a liquid water source, energy, and chemical building blocks. Beneath an ice shell estimated to be 15–25 km thick lies a global ocean that may exceed the depth of all Earth's oceans combined.
The moon is kept geologically active by strong tidal heating from Jupiter. This process may fuel hydrothermal vents on the seafloor, mirroring life-rich environments found on Earth. Furthermore, observations suggest that salts, carbon compounds, and potentially oxygen reach the subsurface ocean through cracks in the ice.
