[ Watch The Video: Radiative Instability of a Geophysical Vortex ] American Institute of Physics French researchers develop sophisticated mathematical model to study the behavior of earthly vortices, like hurricanes and ocean currents What do smoke rings, tornadoes and the Great Red Spot of Jupiter have in common? They are all examples of vortices, regions within a fluid (liquid, gas or plasma) where the flow spins around an imaginary straight or curved axis. Understanding how...

Researchers Break Down Science Behind Plasmas

[ Watch the Video ] Researchers have discovered clues to help give scientists a better understanding of how plasma jets from the sun occur. The team from the Division of Engineering and Applied Science at the California Institute of Technology (Caltech) used high-speed cameras to look at jets of plasma in the lab. During the experiments, they fired jets of hydrogen, nitrogen, and argon plasmas at speeds of about 6 to 30 miles per second across a distance of 8 inches in a vacuum....

Physicists, led by a researcher at the University of Warwick, studying new images of clouds of material exploding from the Sun have spotted instabilities forming in that exploding cloud that are similar to those seen in clouds in Earth's atmosphere. These results could greatly assist physicists trying to understand and predict our Solar System's "weather". The researchers, led by of the Centre for Fusion Space and Astrophysics, at the University of Warwick's Department of Physics, made their...

More accurate simulations could lead to 'break-even' fusion in foreseeable future A new X-ray imaging capability has taken pictures of a critical instability at the heart of Sandia's huge Z accelerator. The effort may help remove a major impediment in the worldwide, multidecade, multibillion dollar effort to harness nuclear fusion to generate electrical power from sea water. "These are the first controlled measurements of the growth of magneto-Rayleigh-Taylor [MRT] instabilities" in fast...

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:
