As the distance varies, so does Jupiter\u2019s gravitational pull, which leads to the moon being relentlessly squeezed. The result: an extreme case of tidal flexing \u2014 friction from tidal forces that generates internal heat.<\/p>\n<p>\u201cThis constant flexing creates immense energy, which literally melts portions of Io\u2019s interior,\u201d said Bolton. \u201cIf Io has a global magma ocean, we knew the signature of its tidal deformation would be much larger than a more rigid, mostly solid interior. Thus, depending on the results from Juno\u2019s probing of Io\u2019s gravity field, we would be able to tell if a global magma ocean was hiding beneath its surface.\u201d<\/p>\n<p>The Juno team compared Doppler data from their two flybys with observations from the agency\u2019s previous missions to the Jovian system and from ground telescopes. They found tidal deformation consistent with Io not having a shallow global magma ocean.<\/p>\n<h4>Implications for Planetary Science<\/h4>\n<p>\u201cJuno\u2019s discovery that tidal forces do not always create global magma oceans does more than prompt us to rethink what we know about Io\u2019s interior,\u201d said lead author Ryan Park, a Juno co-investigator and supervisor of the Solar System Dynamics Group at <span aria-describedby=\"tt\" data-cmtooltip=\"\n\n<div class=glossaryItemTitle>JPL<\/div>\n<div class=glossaryItemBody>JPL stands for the Jet Propulsion Laboratory, a major research and development center funded by NASA and managed by the California Institute of Technology (Caltech).
