For the very first time, powerful Alfvén waves -- magnetic plasma waves -- have been observed in the Sun’s corona. The plasma in the observed waves moves at speeds of 20 km/s and the waves ...

The Alfvén transition zone observed by the Parker Solar Probe in young solar wind – global properties and model comparisons. Journal: Monthly Notices of the Royal Astronomical Society: Letters ...

NASA’s Juno spacecraft has detected an unusual new variety of plasma phenomenon occurring over Jupiter's north pole.

Imaging of Alfvén waves and fast ions in a fusion plasma Date: December 17, 2010 Source: American Physical Society Summary: Fusion plasmas in the laboratory typically reach 100 million degrees.

Habitability depends on more than just a planet's distance from its host star. New research looks at the impact stellar magnetism has on exoplanets.

Scientists had a theory: Alfvén waves. Picture a magnetic field as a web of lines. If you stretch and pull at those lines, an Alfvén wave is what spawns when the lines attempt to snap back into ...

Physicists report definitive evidence that auroras that light up the sky in the high latitudes are caused by electrons accelerated by a powerful electromagnetic force called Alfvén waves.
