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.

   Explanation: It came from [4]outer space. It -- in this case a
   [5]sand-sized bit of a [6]comet nucleus -- was likely ejected many
   years ago from Sun-orbiting [7]Comet Swift-Tuttle, but then continued
   to orbit the Sun alone. When the Earth crossed through this orbit, the
   piece of comet debris impacted the [8]atmosphere of our fair planet and
   was seen as a meteor. This [9]meteor deteriorated, causing gases to be
   emitted that glowed in colors emitted by its component elements. The
   featured image was taken last week from [10]Castilla La Mancha,
   [11]Spain, during the peak night of the [12]Perseids meteor shower. The
   picturesque meteor streak happened to appear in the [13]only one of 50
   frames that also included the [14]Andromeda galaxy. Stars dot the
   frame, each much further away than the meteor. Compared to the stars,
   the [15]Andromeda galaxy (M31) is, again, much further away.
