Rising from a sea of dust and gas, the legendary Horsehead Nebula emerges. This amazing NASA’s Hubble Space Telescope close-up reveals the cloud’s intricate structure. Also known as Barnard 33, the Horsehead is a cold, dark cloud of gas and dust, silhouetted against the bright nebula, IC 434. The bright area at the top left edge is a young star still embedded in its nursery of gas and dust. The top of the nebula also is being sculpted by radiation from a massive star located out of view.
