                        Astronomy Picture of the Day

    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.

    A star-filled sky has two streaks in the foreground. A green and red
    streak toward the lower left was created by an ablating meteor, while
   the blue and white streak on the upper right is the coma and tail of a
      comet. Please see the explanation for more detailed information.

   Explanation: How different are these two streaks? The streak on the
   upper right is Comet Tsuchinshan-Atlas showing an impressive dust tail.
   The comet is a large and dirty iceberg that entered the inner Solar
   System and is shedding gas and dust as it is warmed by the Sun's light.
   The streak on the lower left is a meteor showing an impressive
   evaporation trail. The meteor is a small and cold rock that entered the
   Earth's atmosphere and is shedding gas and dust as it is warmed by
   molecular collisions. The meteor was likely once part of a comet or
   asteroid -- perhaps later composing part of its tail. The meteor was
   gone in a flash and was only caught by coincidence during a series of
   exposures documenting the comet's long tail. The featured image was
   captured just over a month ago from Sichuan Province in China.
