Europa may lack life-supporting seafloor activity due to weak tidal forces, new study suggests.
A new study suggests Jupiter’s moon Europa may lack the seafloor activity needed to support life, as its rocky interior likely lacks tectonic motion or hydrothermal vents due to weak tidal forces.
While Europa has liquid water and tidal heating, researchers say these may not generate enough energy for life-sustaining chemistry.
The findings, based on modeling of the moon’s size, core, and gravity, indicate a geologically quiet ocean floor.
NASA’s Europa Clipper mission, launched in 2024, will conduct close flybys starting in 2031 to test these conclusions.
Scientists remain cautious, acknowledging that future data could change the outlook.
Europa podría carecer de actividad vital en el fondo marino debido a las débiles fuerzas de marea, sugiere un nuevo estudio.
