Subject: Magnetic Fields, Grain Alignment, and You

Observations of polarization caused by dust grains aligned with the
magnetic field is a major tool for studying the magnetic field geometry
in regions ranging in size from entire galaxies, down to planetary
systems and stellar winds. The alignment mechanism, however, has eluded
astronomers for over 50 years. After these years of frustration, we now
seem to be closing in on an understanding of the alignment mechanism,
which I will discuss.
