Day 12. Infrared Horsehead Nebula. Rising like a giant seahorse from turbulent waves of dust and gas in the constellation of Orion is the Horsehead Nebula, otherwise known as Barnard 33. This image shows the region in infrared light, which has longer wavelengths than visible light and can pierce through the dusty material that usually obscures the nebula’s inner regions. The result is a rather ethereal and fragile-looking structure, made of delicate folds of gas—very different from the nebula’s appearance in visible light. The nebula lies 1,300 light-years away from Earth.
