For Magnetic Reconnection Energy, O—not X—Might Mark the Spot

by Mark Zastrow 10 April 201718 July 2023

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.

Stream Network Geometry Correlates with Climate

by Terri Cook 6 April 20176 June 2022

A "big data" analysis of nearly 1 million river junctions in the contiguous United States shows that branching angles in dendritic drainages vary systematically between humid and arid regions.

Why Do Great Earthquakes Follow Each Other at Subduction Zones?

by Terri Cook 31 March 201716 March 2022

A decade of continuous GPS measurements in South America indicates that enhanced strain accumulation following a great earthquake can initiate failure along adjacent fault segments.

Plasma Waves Pinpointed at the Site of Magnetic Reconnection

by Mark Zastrow 17 February 201718 July 2023

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.
