Magnetic 'switchback' detected near Earth for the first time

In recent years, NASA's Parker Solar Probe has given us a close-up look at the sun. Among the probe's revelations was the presence of numerous kinks, or "switchbacks," in magnetic field lines in the sun's outer atmosphere. These switchbacks are thought to form when solar magnetic field lines that point in opposite directions break and then snap together, or "reconnect," in a new arrangement, leaving telltale zigzag kinks in the reconfigured lines.
