On August 1, 2010, almost the entire Earth-facing side of the sun erupted in a tumult of activity. This image of the solar event shows the C3-class solar flare (white area on upper left), a solar tsunami (wave-like structure, upper right), multiple filaments of magnetism lifting off the stellar surface, large-scale shaking of the solar corona, radio bursts, a coronal mass ejection and more. Different colors in the image represent different gas temperatures.Photo: NASA/SDO/AIA
