| Located in the constellation of Orion (The Hunter), 1500 light-years   away from Earth, the Orion Molecular Cloud Complex is the closest region   of massive star formation to Earth, and contains a treasury of bright   nebulae, dark clouds and young stars.  The bright blue patch above of the center of the image is the nebula NGC   1999. This region  is what astronomers   call a reflection nebula, where the pale blue glow of background   starlight is reflected from clouds of dust. The nebula is mainly   illuminated by the energetic radiation from the young star V380 Orionis lurking at its heart (Text from ESO).  Central crop at full resolution here |
