An Orion Deep Field

Adrift 1,500 light-years away in one of
the night sky's
most recognizable
constellations, the glowing
Orion Nebula and the dark
Horsehead Nebula are contrasting
cosmic vistas.

They both appear in this stunning composite digital image
assembled from over 20 hours of data that includes exposures
filtered to record emission from hydrogen

The view reveals extensive
nebulosities associated with
the giant Orion Molecular

, itself hundreds of light-years across.

The magnificent emission region, the
(aka M42), lies at the
upper right of the picture.

Immediately to its left are a cluster of
of prominent bluish
reflection nebulae sometimes called
the Running Man.

The 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.

Fainter tendrils of glowing hydrogen gas are easily traced
throughout the region in
Orion deep field
