The Canada-France-Hawaii Telescope produced this stunning image of the well-known Horsehead Nebula. It is part of an enormous cloud of molecular gas and dust obscuring background light from nearby emission nebula IC 434, producing the silhouette.
The Magnificent Horsehead Nebula. 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.
August 30, 2013: The Cone Nebula (NGC 2264) consists of a glowing cloud of ionized gas excited by the surrounding hot, massive young blue stars. Strong winds of particles blow from these stars, shaping the residual gas left from a spent star formation region, creating these structures with striking appearances.%u2014 Tom Chao
