Although magnetic fields have an important role in the evolution of gas clouds in the Galaxy, the strength and orientation of the field in the interstellar medium near the heliosphere has been poorly constrained, with previous estimates varying widely and based on indirect observational inferences or modelling. Measurements of the deflection of the solar wind plasma flows in the heliosheath are now used to determine the magnetic field strength and orientation in the interstellar medium.
