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.

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.

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

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

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 ...
