Barnard 33, The Horsehead Nebula in Orion
"Sculpted by stellar winds and radiation, a magnificent interstellar dust cloud by chance has assumed this recognizable
shape. Fittingly named the Horsehead Nebula, it is some 1,500 light-years distant, embedded in the vast Orion cloud complex.
About five light-years "tall", the dark cloud is cataloged as Barnard 33 and is visible only because its obscuring dust is
silhouetted against the glowing red emission nebula IC 434. Contrasting blue reflection nebula NGC 2023 is visible on the
lower left." APOD: 2005 November 30 - Reflections on the Horsehead Nebula
