New research suggests that swirling designs on the dusty lunar surface might be the product of electric fields generated by pockets
of magnetic bubbles.
In Earth's magnetosphere — the giant
magnetic bubble surrounding our planet — these magnetic reconnections can fling charged particles toward Earth, triggering auroras.
Alien worlds, like Earth, are shielded from cosmic rays by
magnetic bubbles around their sun — trouble is, stars have a tendency to drop their guard
Since then, the Voyagers have gone on to investigate the outer reaches of the heliosphere, the
giant magnetic bubble created by the sun that envelops the solar system.
Solar wind creates a
huge magnetic bubble, known as the heliosphere, that protects Earth and the other planets from energetic subatomic particles that constantly zip around in deep space.
Far beyond Pluto, beyond even the comets, lies the solar system's true edge — the heliosheath, where charged particles blowing outward from the sun crash into those flowing from other stars to create a vast
protective magnetic bubble.
Scientists have found the first direct evidence for explosive releases of energy in Saturn's
magnetic bubble using data from the Cassini spacecraft, a joint mission between NASA, the European Space Agency, and the Italian Space Agency.
«Can we create and sustain a big -
enough magnetic bubble in a tokamak to support a strong electric current without a solenoid?»
The decrease in pressure from the solar wind deflates the heliosphere, the
huge magnetic bubble that envelops the solar system.
One of the mysteries this gives us clues to answering is how Saturn's
magnetic bubble, known as its magnetosphere, gets rid of gas from Saturn's tiny icy moon Enceladus.
«Explosive energy in Saturn's
magnetic bubble.»
Part of the problem is that we do not know exactly where the boundary of the solar system is — only that it is marked by the edge of
a magnetic bubble known as the heliopause, at which the influence of other stars starts to dominate that of the sun.
Since 2004 Voyager 1 had been travelling through a border zone in the heliosphere,
the magnetic bubble blown by charged particles streaming from the sun.
That process causes storms in
the magnetic bubble around Earth.
The off - kilter tumbling of
the magnetic bubble around Uranus may regularly let a barrage of charged particles from the solar wind flow in
Since then, this four - satellite mission is performing the first and best ever stereo investigation of the Earth's magnetosphere —
the magnetic bubble surrounding our planet.
North of Norway over the Norwegian and Greenland Seas,
the magnetic bubble surrounding the Earth dips inward, allowing space particles to funnel in toward the planet.
However, in a previous study involving Cluster, plasma turbulence was observed in the magnetosheath, the region between Earth's bow shock, where the solar wind meets the magnetic field of the Earth, and the magnetosphere —
the magnetic bubble which surrounds it.
