Europa's Ocean: Life's Spark Dimmed by New Study

A recent study has cast significant doubt on the habitability of Jupiter's moon Europa, a celestial body long considered a prime candidate for harboring extraterrestrial life. Scientists now suggest that Europa's vast subsurface ocean may be geologically inactive, diminishing the likelihood of conditions supporting contemporary life. This challenges earlier theories that pointed to organic compounds and energy sources beneath its icy crust.

The research, led by planetary scientist Paul Byrne, analyzed Europa's size, core composition, and gravitational interactions with Jupiter. The findings indicate that any internal heat sources likely dissipated billions of years ago, and the moon lacks the tidal forces seen on other Jovian moons that drive geological activity. This suggests a quiet seafloor, devoid of active volcanoes or hydrothermal vents, essential for nutrient and chemical energy production that fuels life on Earth.
