"La nebulosa Cabeza de Caballo" (Horsehead Nebula en inglés) o Barnard 33 (B33) .. Es una nube de gas fría y oscura, situada a unos 1.500 años luz de la Tierra, al sur del extremo izquierdo del Cinturón de Orión.. Forma parte del Complejo de Nubes Moleculares de Orión, y mide aproximadamente 3,5 años luz de ancho.. Esta nebulosa oscura es visible por contraste, ya que aparece por delante de la nebulosa de emisión IC 434.. Por su forma es la más familiar de las nebulosas de absorción..



The Sword Of Orion - The Orion constellation is noticeable for three medium-bright stars in a short, straight row. These stars represent Orion’s Belt. If you look closely, you’ll notice a curved line of stars “hanging” from the three Belt stars. These stars represent Orion’s Sword. Look for the Orion Nebula about midway down in the Sword of Orion, otherwise known as M42, a stellar nursery where new stars are being born.


The Horsehead Nebula is some 1,500 ly 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. Stars are forming within the dark cloud.
