It's long been predicted that a solar eclipse would cause a bow wave in Earth's ionosphere. The August 2017 eclipse—called the “Great American Eclipse” because it crossed the continental US— gave scientists a chance to test that prediction. Scientists at MIT's Haystack Observatory used more than 2,000ÃÂ ...

Above the ozone layer, the ionosphere is a part of Earth's atmosphere where particles have been cooked into a sea of electrically-charged electrons and ions by the Sun's radiation. The ionosphere is comingled with the very highest—and quite thin—layers of Earth's neutral upper atmosphere, making thisÃÂ ...

Earth's ionosphere, where incoming cosmic and solar rays interact with the atmosphere to create charged particles, extends from about 75 to about 1,200 kilometers above the planet's surface. From its geostationary orbit 35,000 kilometers high, GOLD will monitor the ionosphere's density and temperatureÃÂ ...

Earth-bound radio telescopes encounter too much interference from electromagnetic pollution caused by human activity, such as maritime communication and short-wave broadcasting, to get a clear signal, and Earth's ionosphere blocks the longest wavelengths from reaching these scopes in the first place.
