NASA detects Earth's long-sought invisible electrical field

NASA has detected an invisible electrical field, termed the "polar wind," surrounding Earth, over 60 years after it was first hypothesized. This field, crucial for atmospheric dynamics, allows particles to escape into space, countering gravity. The Endurance rocket mission measured a slight voltage change at 477 miles altitude, revealing the field's strength is 10.6 times that of gravity, influencing atmospheric evolution. Findings were published on August 28 in *Nature*.
