Document Summary
Solar wind : the continuous flow of charged particles from the sun that permeates the solar system. Aurora a natural electrical phenomenon characterized by the appearance of streamers of reddish or greenish light in the sky, usually near the northern or southern magnetic pole. Heliosiesmology is the study of the propagation of wave oscillations, particularly acoustic pressure waves, in the sun. Unlike seismic waves on earth, solar waves have practically no shear component (s-waves). In other words, the turbulence rings the sun like a bell: --doppler shift, (red and blue shift) a change in frequency due to the doppler effect, the visible light spectrum. Redshift and blueshift describe how light changes as objects in space (such as stars or galaxies) move closer or farther away from us. When an object moves away from us, the light is shifted to thered end of the spectrum, as its wavelengths get longer.
