Study probes coronal origin of solar wind switchbacks

Original: On the coronal origin of magnetic switchbacks in the solar wind

New research published in Nature examines where magnetic switchbacks in the solar wind come from. These sudden, zigzag reversals in the Sun's magnetic field, observed by spacecraft including Parker Solar Probe, have puzzled scientists for years. The study argues that the kinks originate in the Sun's corona rather than forming later in interplanetary space, with researchers debating what the finding means for models of how the solar wind is heated and accelerated.

Why now: A new Nature paper offers evidence on a long-standing mystery about the Sun's magnetic field behaviour
