  It is believed that magnetic field lines are twisted and bend by turbulent
motions in the Galaxy. Therefore, both Galactic synchrotron emission and
thermal emission from dust reflects statistics of Galactic turbulence. Our
simple model of Galactic turbulence, motivated by results of our simulations,
predicts that Galactic disk and halo exhibit different angular power spectra.
We show that observed angular spectra of synchrotron emission are compatible
with our model. We also show that our model is compatible with the angular
spectra of star-light polarization for the Galactic disk. Finally, we discuss
how one can estimate polarized microwave emission from dust in the Galactic
halo using star-light polarimetry.
