Horsehead and Orion Nebulas
Explanation: The dark
Horsehead Nebula and the glowing
Orion Nebula are contrasting cosmic vistas. Adrift 1,500 light-years away in one of
the night sky's most recognizable
constellations, they appear in opposite corners of the above
stunning mosaic. The familiar
Horsehead nebula appears as a dark cloud, a
small silhouette notched against the long red glow at the lower left.
Alnitak is the easternmost star in
Orion's belt and is seen as the brightest
star to the left of the
Horsehead. Below Alnitak is the
Flame Nebula, with clouds of bright emission and
dramatic dark dust lanes. The magnificent emission region, the
Orion Nebula (aka M42), lies at the upper right. Immediately to its left is a prominent
reflection nebula sometimes called the Running Man. Pervasive
tendrils of glowing hydrogen gas are easily
traced throughout the region.
