                        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.

    Large clouds of interstellar gas and dust of various shapes and sizes
     cover the image. A cloud shaped like a bubble sits atop the image,
             while a cloud shaped like a claw is in the middle.

   Explanation: What unexpected things do you see when you look up at the
   night sky? Today’s image resembles an abstract painting, with large
   swaths of color strewn across a cosmic canvas seemingly without design.
   Despite the image's abstract nature, the human mind finds patterns,
   identifying a large claw reaching up towards a floating bubble.
   Embedded within these seemingly random structures are the physical laws
   that govern how light and matter interact. The Claw (Sh2-157) and
   Bubble (NGC 7635) Nebulae glow colors that are mapped to the yellow and
   blue shown, indicating the presence of hydrogen and oxygen ionized by
   the intense light emitted from stars several times the mass of the Sun.
   This image depicts both the chaos and structure of astronomical
   processes, showing that a common thread between art and science is to
   look for the unexpected.
