Each solar cycle might seem like the same old story, but one thing has changed significantly since the previous solar maximum–our technology.
A new study supports the idea of a “helicity barrier” influencing the fluctuating stream of interplanetary plasma.
MESSENGER observations show a 50% rise in atmospheric sodium-group ions during periods of high solar wind activity.
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.
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.
Charged particles escape our atmosphere following Earth’s magnetic field and constitute a main source of matter that modulates Sun-Earth interactions.
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.
While most planetary bow shocks are controlled by the solar wind, at Mars the solar EUV flux is equally important.
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.
This prolific researcher helped us understand the interactions of the solar wind and coronal mass ejections with Earth’s magnetic field.
