We show that in a sufficiently strong magnetic field the QCD vacuum may undergo a transition to a new phase where charged rho(+/-) mesons are condensed. In this phase the vacuum behaves as an anisotropic inhomogeneous superconductor which supports superconductivity along the axis of the magnetic field. In the directions transverse to the magnetic field the superconductivity is absent. The magnetic-field-induced anisotropic superconductivity-which is realized in the cold vacuum, i.e. at zero temperature and density-is a consequence of a nonminimal coupling of the rho mesons to the electromagnetic field. The onset of the superconductivity of the charged rho(+/-) mesons should also induce an inhomogeneous super-fluidity of the neutral rho(0) mesons. We also argue that due to simple kinematical reasons a strong enough magnetic field makes the lifetime of the rho mesons longer by closing the main channels of the strong decays of the rho mesons into charged pions.
