            Moon Mountains Magnified during Ring of Fire Eclipse

   Explanation: What are those dark streaks in this composite image of
   yesterday's solar eclipse? They are reversed shadows of mountains at
   the edge of the Moon. The center image, captured from [5]Xiamen,
   [6]China, has the Moon's center directly in front of the Sun's center.
   [7]The Moon, though, was [8]too far from [9]the Earth to completely
   block the entire Sun. Light that streamed around all of the edges of
   the Moon is called a [10]ring of fire. Images at each end of the
   sequence show [11]sunlight that streamed through lunar valleys. As the
   Moon moved further in front of the Sun, left to right, only the higher
   peaks on the Moon's perimeter could block sunlight. Therefore, the dark
   streaks are projected, distorted, reversed, and magnified [12]shadows
   of mountains at the Moon's edge. Bright areas are called [13]Bailey's
   Beads. Only a narrow swath across Earth's [14]Eastern Hemisphere was
   able to see yesterday's full annular solar eclipse. Next June, though,
   a narrow swath across Earth's [15]Northern Hemisphere will be able to
   see the [16]next annular solar eclipse. A [17]total solar eclipse will
   be [18]visible at the [19]bottom of the world near the end of this
   year.
