There are huge, invisible structures in the ionosphere that are high above the surface of the Earth. These structures are ...

They also want to share what they’re learning about the upper atmosphere by shooting massive amounts of radio waves at it.

Here’s why some people say they hear cracking and popping from an atmospheric event that shouldn’t be able to produce any ...

On November 13, 2020, a pair of European Space Agency spacecraft—Mars Express and the ExoMars Trace Gas Orbiter—set out to gain a deeper understanding of the Martian ionosphere. Utilizing an advanced ...

Red sprites hover between 40 and 55 miles high. Up there, the air is thin, so electric fields can spark gigantic filaments ...

From the ISS, scientists are capturing rare lightning above storms that could impact radio, climate, and safety.

A succession of powerful solar eruptions in early May last year triggered the most powerful solar storm to hit Earth in 20 ...

Radio signals sent between two Mars orbiters—rather than between an orbiter and an Earth-based receiver—capture new insights into atmospheric dynamics.

Recent studies have highlighted the frequent occurrence of sporadic-E (Es) layers—thin, localized zones of enhanced electron density—especially in high-latitude and polar regions. To address this, a ...

The forest breathes! There is a constant exchange of gases, like carbon dioxide and water vapor, between trees, soils and the atmosphere, and scientists measure these exchanges to know where ...

Between 50 and 1,000 kilometers above our heads is the ionosphere, a layer of Earth's upper atmosphere consisting of charged ...

Some of the ions become trapped in a layer of the atmosphere called the ionosphere, where they collide with gas atoms—primarily oxygen and nitrogen—and "excite" them with extra energy.
