Turbulent solar wind originates in the sun's corona, study shows

Solar wind is a never-ending stream of charged particles coming from the sun. Rather than a constant breeze, this wind is rather gusty. As solar wind particles travel through space, they interact with the sun's variable magnetic ...

Light

Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye (about 400–700 nm, or perhaps 380–750 nm.) In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.

Three primary properties of light are:

Light, which exists in tiny "packets" called photons, exhibits properties of both waves and particles. This property is referred to as the wave–particle duality. The study of light, known as optics, is an important research area in modern physics.
