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

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.

GPS positions were off by up to 230 feet during the Gannon Solar Storm in May 2024 in a disruption that lasted for up to two days, a new study has revealed.

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

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

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

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.

Saturn’s upper atmosphere and ionosphere constitute a complex system in which neutral and charged particles interact under the influence of external energy inputs, internal dynamics and ring ...
