The Air Force’s environmental review should conclude in the fall of 2027. If the review goes well, construction of the new ...

A powerful X1.1-class solar flare was released by the sun on March 28, resulting in radio blackouts across North and South America ...

Turkish authorities have denied conspiracy theories suggesting that yesterday's earthquake in İstanbul was artificially ...

SOME years ago considerable discussion took place concerning the relation between the constitution of the ionosphere and its refractive index for radio waves. The question at issue was whether the ...

Despite decades of searching for this signal, astronomers have yet to find it. The problem is that our Earth is too noisy, ...

The ionosphere is home to all of Earth’s charged subatomic particles in its atmosphere. It’s also the highway through which radio waves and GPS signals travel, pinging off gas particles and ...

The ionosphere is the upper portion of Earth's atmosphere consisting of free electrons, which are influenced by solar winds and geomagnetic storms. Radio waves from satellites to Earth travel at ...

A sunspot currently roiling on the side of the sun is slowly turning to face toward our planet, possibly putting us in the firing line for solar flares and subsequent radio blackouts. The sun ...

Computations show that a lower heater frequency would give rise to stronger radiation and the generated VLF radio waves always propagate along the background magnetic field regardless of the dip angle ...

Abstract: Doppler frequency changes for a vertically incident and reflected radio wave caused by a redistribution of electrons in the ionosphere due to drift motions set up by an electric field across ...

As is well known, due to the influence of the geomagnetic field, radio wave propagating through the ionosphere splits into two characteristic waves: the ordinary wave (O-wave) and the extraordinary ...
