WebPreviously it was believed that the fast solar wind originates in the layer where hydrogen becomes ionised, less than 2,000 km above the photosphere. These observations, however, show that bulk outflow has not yet occurred at a height of 5,000 km, but it … WebDec 14, 2024 · In addition to being the birthplace of switchbacks, the scientists think the magnetic funnels might be where one component of the solar wind originates. The solar wind comes in two different varieties – fast and slow – and the funnels could be where some particles in the fast solar wind come from. new grumman sport boat for sale

The fast solar wind originates from coronal holes, [36] which are funnel-like regions of open field lines in the Sun's magnetic field. [37] Such open lines are particularly prevalent around the Sun's magnetic poles. The plasma source is small magnetic fields created by convection cells in the solar atmosphere. See more 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 … 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 … 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 responsible for comets' tails, along with the Sun's radiation. The solar wind contributes to … 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 made the first observations of … 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 solar wind, though their differences extend … See more Alfvén surface The Alfvén surface is the boundary separating the corona from the solar wind defined as where … 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 density. This allowed energetic electrons from the Sun to flow to Earth in narrow beams known as "strahl", which caused a … See more WebMay 19, 2005 · The fast solar wind seems to originate in coronal funnels with a speed of about 10 km/s at a height of 20,000 kilometers above the photosphere".
