solar wind?

Question

I ve heard of this "solar wind" that is released from the sun.
it actually even changes the direction of the tail of commets!

can u please tell me what this solar wind is?
whats it made of and how come it travels thru vacuum space??

Answer 1

A solar wind is a stream of charged particles (i.e., a plasma) which are ejected from the upper atmosphere of a star. When originating from stars other than the Earth's Sun, it is sometimes called a stellar wind.

It consists mostly of high-energy electrons and protons (about 1 keV) that are able to escape the star'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. Many phenomena are directly related to the solar wind, including: geomagnetic storms that can knock out power grids on Earth, auroras, why the tail of a comet always points away from the Sun, and the formation of distant stars.

While early models of the solar wind used primarily thermal energy to accelerate the material, by the 1960s it was clear that thermal acceleration alone cannot account for the high speed solar wind. Some additional acceleration mechanism is required, but is not currently known, but most likely relates to magnetic fields in the solar atmosphere.

Answer 2

The sun boils off particles all the time. Protons and electrons and fragments of atoms make up the solar wind.

Answer 3

the magnetic fields. the solar spots characterize the places the place as quickly as replaced into the north and south poles of the solar, photograph voltaic flares are whilst the magnetic fields brake and launch the photograph voltaic flares trough the photograph voltaic device (nevertheless studying approximately them)

Answer 4

Photons,

AKA light and heat.
