Dusting for Stars’ Magnetic Fingerprints

Caption

ALMA observations of the protoplanetary disk around HD 142527. The white bars show the directions of the magnetic field revealed by the orientation of the dust grains. The strength of the magnetic field is 0.3 milligauss. For comparison, a typical refrigerator magnet has a magnetic field of about 1,000,000 milligauss.
