About the Poster

The Horsehead Nebula, shadowy in optical light, appears transparent and ethereal when seen here at infrared wavelengths. This pillar of tenuous hydrogen gas laced with dust is resisting being eroded away by the radiation from a nearby star. The nebula is a small part of a vast star-forming complex in the constellation Orion. The Horsehead will disintegrate in about 5 million years. Backlit wisps along the Horsehead Nebula upper ridge are being illuminated by Sigma Orionis, a young five-star system just off the top of this image from the Hubble Space Telescope.
