   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, 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 on 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.
