Scientists Observe First 'Switchback' Phenomenon in Earth's Magnetosphere
Scientists have for the first time detected a zigzag-like 'switchback' phenomenon in Earth's magnetosphere, a plasma structure associated with magnetic reconnection events that can influence space weather and potentially disrupt Earth's technological systems. The discovery was made by NASA's MMS spacecraft near the magnetosheath, providing new insights into how solar wind interacts with Earth's magnetic field and improving the ability to predict geomagnetic storms.
