Three-Color Sun

Caption: This photograph shows our sun on June 7, 2011, at the time of an eruption. The source of the eruption glows brightly at lower right. Material blasted outward only to fall back onto the sun's surface. By studying this process, astronomers gained new insights into how young stars grow via stellar accretion. This photo was taken by NASA's Solar Dynamics Observatory. Red shows light at a wavelength of 304 Angstroms, green is 171 Angstroms, and blue is 335 Angstroms.
