Measuring the Magnetic Reconnection Rate in the Magnetotail
Both simulations and observations are used to measure the magnetic reconnection rate in the Earth’s magnetotail, suggesting that the rate is correlated with the intensity of a magnetic substorm.

Cassini Reveals a Missing Link on Saturn’s Rotating Aurora
The bright aurorae dancing in the sky are produced by charged particles traveling along the magnetic field lines from tens of planetary radii. By why do aurorae rotate at Saturn but not at Earth?
