In a significant turn of events, new research led by Dr. Lorenz Roth from KTH Royal Institute of Technology in Sweden questions the existence of water vapour plumes on Europa, Jupiter's icy moon. Initial claims made in 2014 and 2016 suggested that plumes were present, based on observations from the Hubble Space Telescope. However, Roth's latest study, published in Astronomy and Astrophysics, indicates that the confidence in these findings has dropped from 99.9% to below 90%. The reanalysis shows that the emissions may not be from water vapour plumes but could instead be statistical noise influenced by the positioning of Europa in the Hubble images. The study also highlights that the emissions detected could originate from Earth's extended atmosphere rather than from Europa itself. Despite the lack of evidence for plumes, researchers confirm that Europa still likely has a subsurface ocean, heated by tidal forces. The upcoming NASA Europa Clipper mission, scheduled to arrive in 2031, aims to further investigate this moon and provide clarity on its ocean and atmospheric conditions.
