According to a new analysis reported by Hackaday, the apparent water vapor plumes previously detected on Europa, Jupiter's icy moon, appear to have been statistical artifacts. The initial detections had raised hopes of finding habitability markers in the Jovian system, but closer examination suggests the signal was noise rather than genuine outgassing from the moon's subsurface ocean. While the analysis doesn't rule out the existence of water beneath Europa's ice shell—scientists remain confident of that—it does dampen near-term expectations about detecting active plumes from future spacecraft.
