The Electrojet Zeeman Imaging Explorer (EZIE) mission aims to map auroral electrojets, improving scientific models of space ...

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

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 ...

Like Earth, Mars is surrounded by an ionosphere—the part of its upper atmosphere where radiation from the sun knocks ...

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.

NASA is embarking on the Sporadic-E ElectroDynamics (SEED) mission, launching rockets from Kwajalein Atoll to investigate unpredictable Sporadic-E lay ...

For example, air traffic controllers and marine radio users might hear signals from faraway places and mistake them for local ones. Military radar systems can also be misled, detecting “ghost” targets ...

How are Sporadic-E layers formed? The ionosphere, a layer of Earth's atmosphere that stretches from about 60 to 1,000 kilometres, is made up of charged particles or ions.

Researchers mapped Earth’s ionosphere, part of the upper atmosphere, using signal data from 40 million phones – a method that could improve GPS accuracy and help track space weather ...

Eye on the ionosphere The study puts new focus on the ionosphere, a wispy layer of the atmosphere that stretches more than 350 miles above Earth’s surface. It’s a volatile arena: Here, rays from the ...

The ionosphere is a layer of Earth's atmosphere situated between about 37 miles and 620 miles (60 km to 1000 km) in altitude. It is particularly rich in ionized particles, meaning atoms and molecules ...
