These antennas at the High-frequency Active Auroral Research Program (HAARP) facility in Alaska send powerful radio signals into Earth’s ionosphere so that scientists can learn more about it.

Researchers led by Artem Smirnov and Yuri Shprits of the GFZ German Research Centre for Geosciences have presented a new model of the ionosphere in the journal Nature Scientific Reports, developed ...

Discovery in the Overlooked E Layer of the Ionosphere. While much past research has focused on the F layer of the ionosphere — the region where most ionization typically occurs — this study ...

Sporadic E layers are transient, thin regions of enhanced ionisation in the lower ionosphere, predominantly composed of metallic ions originating from meteoric ablation. Their complex dynamics are ...

SpaceX’s rocket explosion in November 2023 created a massive hole in the Earth's ionosphere, providing scientists with a rare opportunity to study its effects.
