      Explanation: This cosmic expanse of dust, gas, and stars covers some 6   
      degrees on the sky in the heroic constellation Perseus. At upper left   
      in the gorgeous skyscape is the intriguing young star cluster IC 348   
      and neighboring Flying Ghost Nebula with clouds of obscuring   
      interstellar dust cataloged as Barnard 3 and 4. At right, another   
      active star forming region NGC 1333 is connected by dark and dusty   
      tendrils on the outskirts of the giant Perseus Molecular Cloud, about   
      850 light-years away. Other dusty nebulae are scattered around the   
      field of view, along with the faint reddish glow of hydrogen gas. In   
      fact, the cosmic dust tends to hide the newly formed stars and young   
      stellar objects or protostars from prying optical telescopes.   
      Collapsing due to self-gravity, the protostars form from the dense   
      cores embedded in the molecular cloud. At the molecular cloud's   
      estimated distance, this field of view would span over 90 light-years.
