An analysis of the electromagnetic "hiss" that surrounds Earth reveals it's not just static; there's a signal hidden within, which may help scientists uncover its source.
NASA's Cassini probe observed vast amounts of plasma on the fringes of Saturn's magnetic field being mysteriously injected hundreds of thousands of kilometers inward.
Scientists have mapped Jupiter's spectacular aurora in unprecedented detail with the Hubble Space Telescope.
New simulations of how thunderstorms drive electrical currents through the Earth's atmosphere combine precision with computational speed.
What business do elves have in the upper atmospheres of gas giants? Plenty, it seems. The enormous ring-shaped phenomena triggered by lightning may occur on Jupiter, Saturn, and exoplanets.
At the edge of Earth's magnetic field, satellites have found X-shaped fields and fast-moving "islands" of magnetism that could shed light on the physics of solar storms.
The decades-old theory of the layers of the Earth's ionosphere, which dates to 1931, has just received an update that takes into account the angle of the Sun.
Researchers could launch an electron beam device into space to study the Earth's magnetic field and trigger artificial auroras and lightning.
Scientists attempting to understand the Earth’s exosphere use a spectrometer to study different types of hydrogen atoms energized by the sun.
