Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

   [2]A person stands looking over a lake. High in a partly cloudy sky is
   the Sun. A close look at the Sun will show that there is a dark spot in
      the center -- the Moon during an annular eclipse. Please see the
                 explanation for more detailed information.

   Explanation: Can you find the Sun? OK, but can you explain why there’s
   a big dark spot in the center? The spot is [5]the Moon, and the
   impressive alignment shown, where the [6]Moon lines up inside the Sun,
   is called an [7]annular solar eclipse. Such an eclipse occurred [8]just
   last week and was visible from a [9]thin swath mostly in [10]Earth's
   southern hemisphere. The featured image was captured from
   [11]Patagonia, [12]Chile. When the Moon is [13]significantly closer to
   the Earth and it aligns with the Sun, a [14]total solar eclipse is then
   visible from parts of the Earth. [15]Annular eclipses are slightly more
   common than total eclipses, but as [16]the Moon moves slowly away from
   the [17]Earth, before a [18]billion more years, the Moon's orbit will
   [19]no longer bring it close enough for a [20]total solar eclipse to be
   seen from anywhere on [21]Earth.
