Updated procedures enable consistent use of a wide network of polar magnetometers to monitor energy flow into the tail of Earth’s magnetosphere during the growth phase of substorms.

First Solar Wind Plasma Observations from the Tianwen-1 Mission
Solar wind plasma data captured by the Tianwen-1 probe while in transit to Mars represent an important step toward a new era of cooperative Martian space exploration.
Hidden Atmospheric Particles Sculpt Near-Earth Space Environment
Charged particles escape our atmosphere following Earth’s magnetic field and constitute a main source of matter that modulates Sun-Earth interactions.
New Results Concerning Solar Wind Entry into the Magnetosphere
A new book describes recent results defining the many pathways and foreshock, bow shock, magnetosheath, and magnetopause phenomena connecting the solar wind to the dayside magnetosphere.
Solar Properties Rival for Control of Mars’s Bow Shock
While most planetary bow shocks are controlled by the solar wind, at Mars the solar EUV flux is equally important.
Understanding the Turbulent Nature of the Solar Wind
Sometimes the conditions in the solar wind can change dramatically over short distances. Satellite observations of these features show that they’re more complex than previously thought.
John T. “Jack” Gosling (1938–2018)
This prolific researcher helped us understand the interactions of the solar wind and coronal mass ejections with Earth’s magnetic field.
How Space Storms Affect the Satellite Superhighway
A powerful numerical model reveals how space weather disturbs magnetic field at geosynchronous orbit.
Evidence That Earth’s Forehead Controls the Wagging of its Tail
Yes, Earth has a tail, a magnetotail, and there is debate about how much Earth’s upper atmosphere plays a role in the controlling the dynamics of this region of space.
Fast CMEs Continue to Decelerate in the Outer Heliosphere
Most fast coronal mass ejections will be decelerated into ambient solar wind quickly in the inner heliosphere, but some of them continue the deceleration with an even larger amplitude beyond 1 AU.
