A friendly reminder for skywatchers in East Asia and the American West: On Sunday May 20 (May 21st across the date line in Asia) the moon will blot out 94 percent of our star’s early evening light in an annular solar eclipse that should leave a dazzling ring of fire in the sky. The solar eclipse won’t be total because the moon will be near its apogee--its farthest point from Earth in its elliptical orbit--but it should still be pretty spectacular. Click through to SPACE.com for a map of the actual path of the eclipse (in the States it will blaze a trail from northern California down to the Texas panhandle) and remember kids: don’t ever look directly into the sun.
