field measurements differ significantly from what we expected, which has implications for the distribution of heavy elements in the interior, including the existence and mass of Jupiter's core,» Bolton said.
Upon exiting the heliopause, the local
measurements of the magnetic
field by Voyager 1, shown here as a compass needle,
differed by 40 degrees from the «true magnetic north» estimated to be the direction of the magnetic
field in the pristine interstellar medium.
