Sun

NASA's High Resolution Coronal Imager, or Hi-C, captured the highest-resolution images ever taken of the sun's corona in the extreme ultraviolet wavelength. The innovative telescope, launched on a sounding rocket at White Sands Missile Range in New Mexico July 11, 2012, focused on a large active region on the sun. The resulting images reveal the dynamic structure of the solar atmosphere in the finest detail ever seen. (NASA)
