For Magnetic Reconnection Energy, O—not X—Might Mark the Spot
A new analysis of satellite data could upend conventional wisdom about how solar storms produce their dangerous radiation—not from X-shaped mergers of magnetic field lines but from swirling vortices.

Explaining Unexpected Twists in the Sun's Magnetic Field
New research shows how the Sun's magnetic field can shift when it approaches Earth, which can throw off space weather forecasts.

Plasma Waves Pinpointed at the Site of Magnetic Reconnection
When the Earth's and the Sun's magnetic fields meet, they realign in explosive and mysterious reconnections. Data suggest that plasma waves called kinetic Alfvén waves play a key role.

First Results from NASA’s Magnetospheric Multiscale Mission
Understanding magnetic reconnection is important in the context of Sun-Earth Connection, because of the resulting exchange of mass and energy, and the large amount of energy involved.

Chasing Down the Slow Solar Wind
The Sun's plasma blasts Earth’s magnetosphere at more than a million miles per hour. The fastest pours from holes in the corona, but until recently the source of the "slow" solar wind was a mystery.

James Wynne Dungey (1923–2015)
Dungey, whose research laid the foundation for how the Sun's magnetic field connects to Earth's magnetic field, died on 9 May 2015. He was 92.
