Using new images with unprecedented detail, scientists have found material rotating around a very young protostar probably has dragged in and twisted magnetic fields from the larger area surrounding the star. The discovery, made with the Very Large Array VLA) radio telescope, has important implications for how dusty disks – the raw material for planet formation – grow around young stars.
The scientists studied a young protostar 750 light-years from Earth in constellation Perseus...
