What is Solar Wind?

Posted by on Friday, December 9, 2016

Solar wind is the continuous flow of charged particles from the sun that permeates the solar system.

This plasma consists of mostly electrons, protons and alpha particles.

A coronal mass ejection (CME) is an unusually large release of plasma and magnetic field from the solar corona. When the ejection is directed towards Earth the solar energetic particles can cause particularly strong aurorae in large regions around Earth's magnetic poles.

From May 10 to May 12, 1999, NASA's Advanced Composition Explorer (ACE) and WIND spacecraft observed a 98% decrease of solar wind density.

On 13 December 2010, Voyager 1 determined that the velocity of the solar wind, at its location 10.8 billion miles from Earth had slowed to zero.
