The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona. This plasma mostly consists of electrons, protons and alpha particles with kinetic energy between 0.5 and 10 keV. The composition of the solar wind plasma also includes a mixture of materials found in … See more Observations from Earth The existence of particles flowing outward from the Sun to the Earth was first suggested by British astronomer Richard C. Carrington. In 1859, Carrington and Richard Hodgson independently … See more Over the Sun's lifetime, the interaction of its surface layers with the escaping solar wind has significantly decreased its surface rotation rate. The wind is considered … See more • From May 10 to May 12, 1999, NASA's Advanced Composition Explorer (ACE) and WIND spacecraft observed a 98% decrease of solar wind … See more While early models of the solar wind relied primarily on thermal energy to accelerate the material, by the 1960s it was clear that thermal acceleration alone cannot account for the high speed of solar wind. An additional unknown acceleration mechanism is … See more Fast and slow solar wind The solar wind is observed to exist in two fundamental states, termed the slow solar wind and the fast … See more Alfvén surface The Alfvén surface is the boundary separating the corona from the solar wind defined as where … See more • Active region • Deep Space Climate Observatory • Dyson–Harrop satellite See more WebApr 22, 2005 · The fast solar wind seems to originate in coronal funnels with a speed of about 10 kms-1 at a height of 20 000 km above the photosphere" .
