solar eclipseA total solar eclipse--a rarity in which the moon completely blocks out the sun--occured Wednesday over Brazil and extended across the Atlantic Ocean, northern Africa, and central Asia where it is ending at sunset in northern Mongolia.
The next total eclipse, on Aug. 1, 2008, will be seen in northern Canada, Greenland, Siberia, Mongolia and northern China. The next total solar eclipse will happen in the United States on Aug. 21, 2017, according to NASA.
An Australian mother and her child wear special protective glasses to watch the solar eclipse from a desert tourist camp in Galo, Libya.
