A Horsehead of a Different Color


This video presents a visualization of the Horsehead Nebula as seen in infrared light. The central Hubble image has been augmented by ground-based observations from the European Southern Observatory’s Visible and Infrared Survey Telescope for Astronomy (VISTA). The stars distributed in the three-dimensional environment in an approximate and statistical manner. While it’s no 100%-accurate, the computer graphics are intended to be scientifically reasonable.

The Horsehead Nebula is a dark cloud of dense gas and dust located just below Orion’s belt. Visible light shows a strong silhouette resembling a horse’s head as used for a knight in chess. As seen at left with infrared light we can see more deeply into the clouds, revealing a more complex scene. The warm parts of the clouds glow in infrared light, and a dark and relatively featureless scene is revealed as a glowing gaseous landscape.
