       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.

      The featured image shows a glowing star forming region rich in glowing   
       gas and dark dust. Two dusty pillars on the right resemble tadpoles.   
             Please see the explanation for more detailed information.

      Explanation: What's causing the commotion in the Tadpole Nebula? Star   
      formation. Dusty emission in the Tadpole Nebula, IC 410, lies about   
      12,000 light-years away in the northern constellation of the Charioteer   
      (Auriga). The cloud of glowing gas is over 100 light-years across,   
      sculpted by stellar winds and radiation from embedded open star cluster   
      NGC 1893. Formed in the interstellar cloud a mere 4 million years ago,   
      bright newly formed cluster stars are seen all around the star-forming   
      nebula. Notable on the lower-right of the featured image are two   
      relatively dense streamers of material trailing away from the nebula's   
      central regions. Potentially sites of ongoing star formation in IC 410,   
      these cosmic tadpole shapes are about 10 light-years long. The image   
      was processed highlighting the emission from sulfur (red), hydrogen   
      (green), and oxygen (blue) gas -- but with the stars digitally removed.
