Researchers reproduce plasma loops to help understand solar physics
Researchers at a recent worldwide conference on fusion power have confirmed the surprising accuracy of a new model for predicting the size of a key barrier to fusion that a top scientist at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) has developed.
Magnetic turbulence is most likely the reason that solar wind moving away from our sun and our solar system is hotter than it theoretically should be, according to new research from scientists at the University of Warwick.
The first controlled studies of extremely hot, dense matter have overthrown the widely accepted 50-year old model used to explain how ions influence each other's behavior in a dense plasma.
The Universe is filled with plasma, a charged gas consisting of ions and electrons. Thin sheets, or boundaries, with currents separate large plasma regions. These boundaries are where most of the exciting action in space happens.
Exploiting a favorable configuration of ESA's Cluster mission spacecraft, scientists have detected and characterized lower hybrid drift waves, a special kind of plasma waves that develop in thin boundaries both in space and in the laboratory.

The Sun and the dynamic space weather system that envelops the Earth are what researchers are trying to get a better understanding of with the help of Heliophysics nuggets.
[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online A new NASA mission set to launch in August 2012 called the Radiation Belt Storm Probes (RBSP) will keep its eye focused on plasma. Ninety-nine percent of the universe is made of this electrified gas, but when it comes to the Earth it is more absent than present. There are two giant donuts of plasma surrounding Earth trapped within a region known as the Van Allen Radiation Belts. The belts are close to...
Hannes Olof GÃ¶sta AlfvÃ©n (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in NorrkÃ¶ping, Sweden. AlfvÃ©n received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves." He was originally trained as an electrical power engineer and later moved on to research and teaching in the fields of plasma physics. AlfvÃ©n made many contributions to plasma physics, including theories describing the...
Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...
Solar Prominence -- Solar prominences are large arch-shaped structures observable in the solar corona. These often have a twist and occasionally become unstable, ejecting plasma and magnetic flux out from the sun. The physics of solar prominence instability is believed to be governed by magnetic forces and magnetic helicity issues. It is thought that instability occurs when a magnetic flux tube becomes excessively twisted. ----- Click here to learn more on this topic from eLibrary:
