Hannes Olof Gösta Alfvén (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in Norrköping, Sweden. Alfvén 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...

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...

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...

Word of the Day
  • In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
  • In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
The word 'postliminy' comes from a Latin word meaning 'threshold'.
