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 red tinged nebula is shown in front of a starfield. Dust
     structures appear around the nebula's edge, and stars are also seen
   near the nebula's center. Please see the explanation for more detailed
                                information.

   Explanation: Stars are forming in the Soul of the Queen of [4]Aethopia.
   More specifically, a large star forming region called the [5]Soul
   Nebula can be found in the direction of the [6]constellation
   Cassiopeia, whom Greek mythology credits as the [7]vain wife of a King
   who long ago ruled [8]lands surrounding the [9]upper Nile river. Also
   known as Westerhout 5 (W5), the [10]Soul Nebula houses several open
   [11]clusters of stars, ridges and [12]pillars darkened by cosmic
   [13]dust, and huge evacuated bubbles formed by the winds of young
   massive [14]stars. Located about 6,500 light years away, the [15]Soul
   Nebula spans about 100 [16]light years and is usually [17]imaged next
   to its celestial [18]neighbor the [19]Heart Nebula (IC 1805). The
   [20]featured image is a composite of exposures made in different
   colors: red as emitted by [21]hydrogen gas, yellow as emitted by
   [22]sulfur, and blue as emitted by [23]oxygen.
