Europa's water plumes become less certain as scientists revise decades-old Hubble analysis

Researchers who initially detected water eruptions from Jupiter's moon Europa in 2014 have reexamined fourteen years of Hubble Space Telescope observations. Upon reanalysis, the evidence now appears to be statistical noise rather than genuine geysers, prompting a dramatic reduction in confidence from 99.9% to below 90%. The reassessment raises questions about one of the most compelling features in the outer solar system's exploration.
