A picture taken on May 21, 2012 shows an annular eclipse in the sky of Taipei. The path of the eclipse will span “a 240 to 300 kilometre-wide (150-185 mile) track that traverses eastern Asia, the northern Pacific Ocean and the western United States”, according to the US space agency. The eclipse begins at sunrise in southern China at 2206 GMT on May 20 and swiftly travels eastward to the southern coast of Japan, NASA said.
