Story summary

NASA's Magnetospheric Multiscale (MMS) mission detected a near-Earth magnetic switchback using data from four satellites.
The switchback forms when solar wind magnetic field lines reconnect with Earth's field, producing a zigzag.
Findings suggest switchbacks influence space weather, potentially triggering geomagnetic storms and auroras.
Study advances understanding of magnetic reconnection and energy transfer; future missions may study switchbacks on other planets.
