Gravity is no longer a mystery to physicists—at least when it comes to large distances. Thanks to science, we can calculate the orbits of planets, predict tides, and send rockets into space with ...

A rocket team reports the first successful detection of Earth’s ambipolar electric field: a weak, planet-wide electric field as fundamental as Earth’s gravity and magnetic fields. First hypothesized ...

Using observations from a NASA suborbital rocket, an international team of scientists has, for the first time, successfully measured a planet-wide electric field that is as fundamental to Earth as ...

NASA scientists have discovered an electric field encompassing Earth’s atmosphere that is as “fundamental” as gravity — and could even give clues about possible life on other planets.

A new planet-wide electric field that is as fundamental to Earth as gravity has been discovered in a major scientific breakthrough. The ambipolar electric field, which begins 150 miles above the ...
