Summary

Story summary

NASA's Magnetospheric Multiscale Mission (MMS) discovered a magnetic switchback near Earth in the magnetosheath.
Led by astrophysicist Emily McDougall, the study examines magnetic reconnection between Earth's and Sun's fields.
The switchback contains high-energy electrons from Earth's field mixed with solar plasma, enabling easier study of reconnection events.
The findings, published in the Journal of Geophysical Research, note that reconnection can disrupt power grids and satellites.
