How dust movement is helping us understand magnetic fields and planet formation - study
Planets originate from protoplanetary disks, circulating disks of gas and dust that develop around young stars, a recent study revealed.
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(photo credit: ALMA (ESO/NAOJ/NRAO), S. Ohashi et al.)
