The UVIS images, which are also being analyzed by team associate Aikaterini Radioti at the University of Liege, Belgium, also suggest that one way the bright auroral storms may be produced is by the formation of new connections between magnetic field lines.

That's because ions spiral along Jupiter's magnetic field lines, and the lines that loop out to 2 million kilometers pierce the planet's surface at latitudes well away from the poles.

Physicists believe that the explanation lies in giant waves that spread into space along the Sun's magnetic field lines, making them wobble like a washing line yanked hard at one end.

Particles, including electrons, in the solar outburst can penetrate the ionosphere, following Earth's magnetic field lines, which converge at the poles.

A team of researchers at the Brazilian Center for Physics Research is studying the motion of vortex domain walls — local regions of charge that collectively store information via their configuration — driven by magnetic fields in ferromagnetic nanowires, which are configured in a straight line with an asymmetric Y - like branch.

Travis Horton at the University of Canterbury, New Zealand, plotted the migratory tracks from each species over a detailed magnetic map of Earth, which shows how the magnetic field's inclination and declination — the angular difference between the field lines and true north — vary from point to point.

Jets are narrow streams of gas that emergefrom the cores of some galaxies, travel at more than 99 percent thespeed of light, and penetrate as much as several million light - yearsinto intergalactic space before fanning out into broad, luminous lobes.How might a black - hole whirlpool generate such a pair of waterspouts?Swirling bundles of magnetic field lines, flinging particles outwardfrom the poles of the hole, provide a natural explanation.

Over time they build a more detailed magnetic map by learning to recognise variations in the strength and direction of the field lines, which are angled more steeply towards the poles and flatter at the magnetic equator.

Given the corona is not expected to change much before the eclipse, scientists at the NSO used current observations to create a coronal magnetic model that shows where they expect to see field lines concentrated during the eclipse.

Team member Robert Erdélyi at the University of Sheffield, UK, says that energy is probably channelled in the form of magnetic disturbances called torsional Alfvén waves, which race up the twisted field lines of the tornado to be dissipated as heat in the corona.

But Paty found that when this wind blows towards Uranus at the right angle, the planet's magnetic field lines up with the solar wind's and lets particles through.

This channel is especially good at showing coronal loops - the arcs extending off of the Sun where plasma moves along magnetic field lines.

The neutron star's magnetic field lines converge at the magnetic poles, so the charges get focussed and a narrow cone of non-thermal radiation is beamed outward.

Researchers produce such heating by aiming microwaves at the electrons gyrating around magnetic field lines — a process that increases the thermal energy of the electrons, transfers it to the ions through collisions, and supplements the heating of the ions by neutral beam injection.

Then, immediately afterwards, Earth's magnetic field lines vibrate at ultra-low frequencies to further accelerate the electrons — and all that can happen in just 15 minutes.
