Scientists measured a chorus wave emerging from an unexpected place, and confirmed a key piece of a theory about how these ...

RECENT radio observations of Jupiter, in the frequency-range 14–27 Mc./s., have suggested the presence of an ionosphere and a magnetic field on the planet. If the magnetic field is regarded as ...

Jupiter’s poles have long been a focus ... these vortices originate in the ionosphere, where friction in magnetic field lines induces rotational motion. This energy propagates downward ...

The planet's fast spin on its axis means that one Jupiter day lasts less than 10 Earth hours, and it sparks electrical currents that may drive the planet's intense and massive magnetic field ...

"Most of the external layers of a massive star are removed during the supernova, but some material falls back, making the neutron star spin faster." ...

Astronomers have finally unlocked a crucial piece of the planet formation puzzle by detecting the magnetic fingerprint of a young star’s protoplanetary disk. Using ALMA, researchers observed how dust ...

Scientists have uncovered the long-sought mechanism behind low-field magnetars, showing that supernova fallback material ...

Astronomers have succeeded in observing the magnetic field around a young star where planets are thought to be forming. The team was able to use dust to measure the three-dimensional structure ...

Aurorae the result of charged particles—electrons, protons or ions—being accelerated along a planet’s magnetic field lines ... as happens around Earth, Jupiter, Saturn and Uranus.

This gives Jupiter a powerful magnetic field, with an influence stretching for millions of kilometres beyond the planet. Electrically-charged particles, some from the Sun and others from Jupiter's ...
