   Explanation: Stars are forming in Lynds Dark Nebula ([5]LDN) 1251.
   About 1,000 light-years away and drifting above the plane of our Milky
   Way galaxy, LDN 1251 is also less appetizingly known as "The Rotten
   Fish Nebula." The dusty molecular cloud is part of a complex of dark
   nebulae mapped toward the [6]Cepheus flare region. [7]Across the
   spectrum, astronomical explorations of the obscuring interstellar
   clouds reveal energetic shocks and outflows associated with newborn
   stars, including the telltale reddish glow from scattered
   [8]Herbig-Haro objects hiding in the image. Distant background galaxies
   also lurk in the scene, almost buried behind the dusty expanse. [9]This
   alluring view spans over four full moons on the sky, or 35 light-years
   at the estimated distance of LDN 1251.
