Magnetic Field Diagram (image) NASA/Goddard Space Flight Center Share Print E-Mail Caption Near Earth's magnetic poles, some of Earth's magnetic field - shown as red in this diagram - loops out into space and connects back to Earth. But some of Earth's polar magnetic field connects directly to the sun's magnetic field, shown here in white. Balloons from NASA's BARREL mission mapped the boundary between these two types of magnetic connection as it shifted and changed during an event called a solar storm.
