flag Europa may lack life-supporting seafloor activity due to weak tidal forces, new study suggests.

flag 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. flag While Europa has liquid water and tidal heating, researchers say these may not generate enough energy for life-sustaining chemistry. flag The findings, based on modeling of the moon’s size, core, and gravity, indicate a geologically quiet ocean floor. flag NASA’s Europa Clipper mission, launched in 2024, will conduct close flybys starting in 2031 to test these conclusions. flag Scientists remain cautious, acknowledging that future data could change the outlook.
