A new tool for tracking coronal mass ejections away from the Sun opens a path toward more accurate warnings for operators who have to cope with adverse space weather.Read More »Space Science & Space Physics
Radio waves are providing a new way to probe the Sun and suggest that the magnetic field of its corona may be stronger than long thought.Read More »Space Science & Space Physics
A Japanese satellite reveals rapid and surprisingly frequent transport of molecular ions from the ionosphere to the magnetosphere, under not only extreme but also moderate geomagnetic conditions.Read More »Space Science & Space Physics
As thunderstorm updrafts strengthen, electrification of clouds can heat the lower ionosphere, explaining prolonged disturbances to radio waves in the rarefied atmospheric layer.Read More »Space Science & Space Physics
Predicting when solar storms will hit Earth remains a tricky business. To help, scientists can now submit their forecasts of coronal mass ejections online as they unfold in real time.Read More »Natural Hazards
A retrospective cohort analysis of anomalies on the Czech power grid shows they are more common during enhanced geomagnetic activity, the first time such impacts have been identified outside the USA.Read More »Space Science & Space Physics
Studying shock precursors in a laboratory setting enables researchers to take a different look at the precursors’ properties and the physics behind them.Read More »Space Science & Space Physics
In the tightly confined region between the innermost ring and the planet’s upper atmosphere, the Cassini spacecraft observed signatures of a previously undetected current system.Read More »Space Science & Space Physics
In the latest episode of its Centennial series, AGU’s Third Pod from the Sun talks space weather and its influence on global policy with Delores Knipp.Read More »Space Science & Space Physics
Lunar samples reveal that the Sun spun relatively slowly in its first billion years and blasted the Earth and Moon with coronal mass ejections.Read More »
