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

Scientists studying the zone between Earth’s atmosphere and space have spotted unusual X- and C-shaped features that could ...

Each day, radio signals from key communications and navigation satellites travel freely through a layer of Earth’s atmosphere known as the ionosphere. Floating 50 to 400 miles (80 to 643 ...

The ionosphere is a layer of the atmosphere around 50 to 400 miles above, filled with charged atoms (ions). These ions reflect and refract radio signals, ...

Extending some 50 to 400 miles above the Earth’s surface, the ionosphere is our world’s interface with space, as our life-supporting atmosphere gives way to a complex environment of ...
