Caption: This photograph from NASA's Solar Dynamics Observatory catches the beginning of the eruption that took place on June 7, 2011. At lower right, dark filaments of solar plasma arc away from the sun. The plasma lofted off, then rained back down to create "hot spots" that glowed in ultraviolet light. This representative-color image shows light at a wavelength of 171 Angstroms (17.1 nm).
