SPACE-US-SPITZER-HORSEHEAD
In this newly released image obtained on December 20, 2014, from NASA's Spitzer Space Telescope, the famous Horsehead nebula (upper right) makes a ghostly appearance on the far right side of the image, but is almost unrecognizable in this infrared view. In visible-light images, the nebula has a distinctively dark and dusty horse-shaped silhouette, but when viewed in infrared light, dust becomes transparent and the nebula appears as a wispy arc. The Horsehead is only one small feature in the Orion Molecular Cloud Complex, dominated in the center of this view by the Flame nebula (NGC 2024). The smaller, glowing cavity falling between the Flame nebula and the Horsehead is called NGC 2023. These regions are about 1,200 light-years away. In this infrared image, blue represents light emitted at a wavelength of 3.6-microns, and cyan (blue-green) represents 4.5-microns, both of which come mainly from hot stars. Green represents 8-micron light and red represents 24-micron light. Relatively cooler objects, such as the dust of the nebulae, appear green and red.
