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 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 [4]Comet Tsuchinshan-Atlas showing an [5]impressive dust
   tail. The [6]comet is a large and dirty iceberg that entered the inner
   [7]Solar System and is [8]shedding gas and dust as it is warmed by the
   Sun's light. The streak on the lower left is a [9]meteor showing an
   impressive [10]evaporation trail. The meteor is a small and cold rock
   that entered the [11]Earth's atmosphere and is shedding gas and dust as
   it is [12]warmed by molecular collisions. The meteor was likely once
   part of a comet or [13]asteroid -- perhaps later composing part of its
   tail. The meteor was [14]gone in a flash and was only caught by
   coincidence during a series of exposures documenting the [15]comet's
   long tail. The featured image was captured just over a month ago from
   [16]Sichuan Province in [17]China.
