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

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

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

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.

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

Researchers in China have developed a way of locating giant "equatorial plasma bubbles" in the ionosphere by analyzing the ...

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

Ionosphere: The ionised layer of Earth’s upper atmosphere, critical for radio communications, where electron density variations influence signal propagation.

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