The constellation of Orion is one of the most recognizable patterns in our night sky. Within its boundaries lies the Orion molecular cloud complex some 1500 light years away. Inside this complex on the farthest eastern edge of Orion's belt is one of the most photograph Nebulae in astronomy. The horse head Nebula. This Nebula was first recorded in 1888 by Scottish astronomer Willemina Fleming at the Harvard College Observatory and ever since we have been captivated by it. The red or pinkish glow originates from hydrogen gas predominantly behind the Nebula, ionized by the nearby bright star Sigma Orionis, which is really a young five star system just out of view. The darkness of the horse head is caused mostly by thick dust although the lower part of the horse head's neck casts a shadow to the left. Streams of gas leaving the Nebula are funneled by a strong magnetic field. Bright spots in the horse head Nebula's base are young stars just beginning to form. Since 1888 this has been our main view of the horse head Nebula and it has become an icon. But in April 2013 astronomers using the Hubble Space Telescope released another view, one that only Hubble's infrared cameras in space could provide. Here is the horse head Nebula and the infrared. In the Hubble image the backlit wisps along the horse head's upper ridge illuminated by Sigma Orionis can be seen. Two fledgling stars peek out from their now exposed nurseries. This Nebula gets its shape from powerful forces within this stellar cradle. Harsh ultraviolet radiation from one of these bright stars is slowly evaporating the Nebula. Gas clouds surrounding the horse head already have dissipated but the tip of the jutting pillar contains a slightly higher density of hydrogen and helium laced with dust. This cast a shadow that protects material behind it from being stripped away by intense stellar radiation evaporating the hydrogen cloud and a pillar structure forms. The Hubble Space Telescope has been providing us with groundbreaking science for two decades. And every once in a while it takes time out to give us a portrait of familiar friends in a completely new light.
