Beneath the bogs of New Zealand’s Northland is a massive Ngāwhā kauri, living from 41,000 to 42,500 years ago, which gives an isolated, unbroken record of a period when Earth’s magnetic field declined ...

Scientists convert Earth's magnetic field collapse from 41,000 years ago into chilling audio, revealing ancient cosmic ...

Shaped like two enormous donuts, the Van Allen belts are a big, energetic stew of charged particles that encircle Earth. The particles of the outer belt come from the sun by means of solar wind and ...

The zones are essentially restricted to the sunlit magnetosphere. They form a kind of cusp radiation ring/belt, where a proton drifts with a period of several minutes, conserving its 1st and the 2nd ...

The public is enamored of images returned to Earth by space probes. Whether they show the moons of Jupiter, the rings of Saturn, or the icy surface of Pluto, these captivating images garner loads ...

The result of these interfering fields is an overall magnetosphere that’s asymmetric and messy. If a magnetosphere does its job well, it shields a planet from gouging by the sun.

Such a mission would help us unravel the nature of Uranus’s magnetosphere and its interaction with the planet’s atmosphere, moons and rings, and with the solar wind. “Of course, modern instrumentation ...

An Earth-Rocking Cosmic Explosion Turns 20 Twenty years ago today a magnetar’s epic tantrum made our planet ring like a bell from tens of thousands of light-years away ...

In Earth's inner magnetosphere where the plasmasphere, ring current and radiation belts overlap, energy and momentum are exchanged between different plasma populations by plasma waves. Resonant ...

According to Jamie Jasinski, a space plasma physicist at the NASA Jet Propulsion Laboratory, past space voyages have provided mysterious readings about the exact nature of the Uranus magnetosphere.

Uranus has a set of rings and 27 known moons, most of which are named after characters from Shakespeare’s plays. While its rings aren’t as flashy as Saturn’s, they’re still pretty interesting. And ...
