Life in color
Red, the color of human blood, symbolizes passion, fire, love, and anger. In Eastern cultures, it also connotes luck and prosperity. Red occurs throughout nature, from dying stars to dying leaves, and humans have evoked its powers for everything from politics to sports.Here, a brilliant red sea fan coral spreads behind a golden damselfish in waters off Fiji’s Namenalala Island

The seething turmoil in our sun's atmosphere is captured in extreme ultraviolet light by NASA's Solar Dynamics Observatory (SDO), launched in 2010 to better understand solar activity and its impact on Earth. In this colorized view (NASA color-codes SDO images to represent different wavelengths of light), bright coronal loops arc between regions of intense magnetic activity, while cooler, darker filaments hang suspended in the sun's magnetic field.Photograph by NASA Solar Dynamics Observatory (SDO)

Captured from about 400 miles (630 kilometers) above Earth by Japan's Hinode satellite, the moon moves into position for the May 20-21 annular solar eclipse.Before the eclipse, astronomer Anthony Cook, of the Griffith Observatory in California, had predicted that scientists would make use of the event to study the sun's activity. Hinode's handlers also used the eclipse to gather data to improve the craft's ability to image subtle features in the sun's corona, or upper atmosphere, according to NASA

Seen from one of Japan's MTSAT meteorological satellites, the shadow of the moon darkens part of the North Pacific during the annular solar eclipse last Sunday and Monday. Despite the diminutive shadow shown, the moon is actually a little bigger than a quarter the size of Earth.An annular eclipse happens when the moon lines up between Earth and the sun, and when the dark moon's apparent diameter is smaller than the visible disk of the sun, leaving a ring—or annulus—of fiery light around the edges.
