News on Interstellar grain alignment

Largely based on spectro-polarimetry obtained with ALFOSC and photo-polarimetry made with Turpol at the Nordic Optical Telescope, a team led by Dr. B-G Andersson finds that intense molecular hydrogen formation makes dust spin and align up with the magnetic field.
