IN SPACE - MAY 20: In this handout provided by NASA, sun spots are seen as the moon moves into a full eclipse position after reaching annularity during the first annular eclipse seen in the U.S. since 1994 on May 20, 2012. Differing from a total solar eclipse, the moon in an annular eclipse appears too small to cover the sun completely, leaving a ring of fire effect around the moon. The eclipse is casting a shallow path crossing the West from west Texas to Oregon then arcing across the northern Pacific Ocean to Tokyo, Japan. (Photo by JAXA/NASA/Hinode via Getty Images)

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. (Sam Yeh/AFP/GettyImages)

A partial solar eclipse as seen during sunrise in the coastal town of Gumaca, Quezon province, southeast of Manila on May 21, 2012. Thousands turned their eyes to the sky on both sides of the Pacific to gaze excitedly as a partial eclipse occluded the sun at dawn in Asia and at dusk in the western US. An annular eclipse occurs when the moon passes in front of the sun, but is too far from the Earth to block it out completely, leaving a 'ring of fire' visible. (Photo: Ted Aljibe/AFP/GettyImages)
