Uranus's upper atmosphere has been cooling for decades—and now scientists have shown why. Observations from Earth have shown ...

Experts are shocked with this Ancient Greek invention that could be the end of solar panels as we know: It produces energy ...

Weak electric field discovered in Earth's atmosphere. Electric field crucial to understanding polar wind flow. Field could explain why Earth is habitable.

Without its magnetic field, life on Earth would not be possible since this shields us from harmful cosmic radiation and charged particles emitted by the Sun, a steady stream known as solar wind.

The solar wind is a steady stream of charged particles—mostly protons and electrons—that come from the sun. H + ions, which are simply protons, are the most abundant particles in the solar ...
