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
