On March 29, a partial solar eclipse swept across parts of the Northern Hemisphere. The edge of the moon's shadow passed across Greenland, most of Europe, northern Asia, northwestern Africa and northeastern North America, including parts of 13 U.S. states.
A partial solar eclipse occurs when the moon passes between Earth and the sun but only partially covers the sun's disk. Unlike in a total solar eclipse, the moon didn't completely block out the sun this time, so observers needed equipment such as eclipse glasses or pinhole cameras to view the sun safely.
