Dubbed the Horsehead nebula because of its obvious resemblance to a steed or chess piece in profile,  this dark cloud of gas and dust sits 1,500 light years from Earth in the winter constellation Orion and has been a favorite target for generations of backyard stargazers.
Now thanks to the Hubble’s  infrared vision of its high-resolution Wide Field Camera,  we finally get to lift the veil of gas and dust covering a nursery of newborn stars buried within the nebula.
In this new portrait, the nebula’s  normally shadowy facade seen in optical light,  now appears in infrared light to be transparent, and lit up against a backdrop of more distant bright nebulae and star clusters scattered in our Milky Way galaxy.
The wispy outline along the outer ridge of this distinctively shaped pillar of hydrogen gas and dust glows due to a nearby, hot, young five star system lying just off the frame.
Astronomers believe that the radiation from these same stars that showcase the Horsehead today will eventually kill it off- evaporating it over time. But no need to worry since astronomers estimate that will be about 5 million years before it completely disappears from our skies.
