Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...

In practice, engineers apply large safety margins to account for surges and aging. Common materials include Kapton (polyimide film), Nomex, black aluminum foil, and ceramics. Each material provides a ...

NASA just launched rockets into the northern lights and captured the hidden electricity that powers them.
