solar wind: The Sun continually gives off charged particles. When these particles leave the corona and head into space, they are called the solar wind. These particles stream outward from the Sun at over 400 miles per second (640 km/sec). They reach the planets and beyond. Because it carries an electric charge, the solar wind affects the magnetic fields of the planets. Solar flares produce powerful bursts of charged particles, creating gusts in the solar wind.
spectrum: One of the ways energy may be given off from an object is as electromagnetic radiation. Electromagnetic radiation takes the form of waves. Electromagnetic waves are measured by the length of the wave called the wavelength. The range of wavelengths emitted by an object is called the object's spectrum. For example, the Sun emits energy in many different wavelengths. Solar radiation
