Solar wind

current of plasma flowing from the sun

The solar wind is a stream of charged particles (i.e., a plasma) which are ejected from the upper atmosphere of the sun. It consists mostly of high-energy electrons and protons (about 1 keV) that are able to escape the sun's gravity in part because of the high temperature of the corona and the high kinetic energy particles gain through a process that is not well understood at this time.

Noun
1. a stream of protons moving radially from the sun
(hypernym) solar radiation
(part-holonym) interplanetary medium
(substance-meronym) interplanetary gas

A steady stream of charged particles that boil off the sun's outer atmosphere and which stream away along magnetic field lines which lead into the interplanetary medium. It is composed of charged particles such as protons , electrons and helium nuclei. When these particles become trapped in the Earth's magnetic field they can cause aurorae when they stream down to earth at the magnetic poles and optically excite atoms and molecules in the upper atmosphere.
