Description
The behavior of the observed polarization amplitudes with spatial
resolution is a strong constraint on the nature and organization of
solar magnetic fields below the resolution limit. We study the
polarization of the very quiet Sun at different spatial resolutions
using ground- and space-based observations. It is shown that 80% of the
observed polarization signals do not change with spatial resolution,
suggesting that, observationally, the very quiet Sun magnetism remains
the same despite the high spatial resolution of space-based
observations. Our analysis also reveals a cascade of spatial scales for
the magnetic field within the resolution element. It is manifest that
the Zeeman effect is sensitive to the microturbulent field usually
associated with Hanle diagnostics. This demonstrates that Zeeman and
Hanle studies show complementary perspectives of the same magnetism.

Solar and Stellar Magnetism
Magnetic fields are at the base of star formation and stellar structure and evolution. When stars are born, magnetic fields brake the rotation during the collapse of the mollecular cloud. In the end of the life of a star, magnetic fields can play a key role in the form of the strong winds that lead to the last stages of stellar evolution. During

Magnetism, Polarization and Radiative Transfer in Astrophysics
Magnetic fields pervade all astrophysical plasmas and govern most of the variability in the Universe at intermediate time scales. They are present in stars across the whole Hertzsprung-Russell diagram, in galaxies, and even perhaps in the intergalactic medium. Polarized light provides the most reliable source of information at our disposal for the
