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]The featured image shows the interstellar dust structures that occur
    on in interior of NGC 281, the Pacman Nebula. The dark structures are
    seen against a red glowing background. Please see the explanation for
                         more detailed information.

   Explanation: Stars can create huge and intricate [5]dust sculptures
   from the dense and dark [6]molecular clouds from which they are born.
   The tools the stars use to carve their detailed works are [7]high
   energy light and fast [8]stellar winds. The heat they generate
   evaporates the dark molecular [9]dust as well as causing ambient
   [10]hydrogen gas to disperse and [11]glow red. [12]Pictured here, a new
   open cluster of stars designated [13]IC 1590 is nearing completion
   around the intricate [14]interstellar dust structures in the emission
   nebula [15]NGC 281, dubbed the [16]Pac-man Nebula because of its
   [17]overall shape. The dust cloud on the upper left is classified as a
   [18]Bok Globule as it may [19]gravitationally collapse and form a star
   -- or stars. The Pacman Nebula lies about 10,000 [20]light years away
   toward the [21]constellation of Cassiopeia.
