In other cases, another member of the system will go on to form a second white dwarf. If gravitational instabilities bring ...

A recent breakthrough in planetary science reveals the first-ever detection of lithium in Mercury’s exosphere—a result ...

One of the less familiar aspects of both planets is that they possess an ionosphere — a layer of ionized (electrically charged) particles — in their upper atmospheres.

But the total solar eclipse will also have imperceptible effects, such as the sudden loss of extreme ultraviolet radiation from the Sun, which generates the ionized layer of Earth's atmosphere ...

If we're to land humans on Mars in the coming decades, we'll have to know what challenges await them when they get there.

Scientists have released the closest images ever to the sun, captured by NASA’s Parker Solar Probe flying 3.8 million miles ...

High-frequency TV waves have long been considered undependable at more than line-of-sight distances, i.e., from transmitter to horizon. They punch through the ionosphere (ionized layers in the ...
