The Horsehead Nebula in Infrared from Hubble
Explanation:
While drifting through the cosmos,
a magnificent interstellar dust cloud became sculpted by
stellar winds and radiation to assume a
recognizable shape.
Fittingly named the
Horsehead Nebula, it is embedded in the
vast and complex Orion Nebula (M42).
A potentially rewarding but difficult object to
view personally
with a small telescope, the
featured gorgeously detailed image was
taken in
infrared light
by the orbiting
Hubble Space Telescope.
The
dark molecular cloud, roughly 1,500
light years distant, is
cataloged as Barnard 33 and is seen above primarily because it is backlit by the
nearby massive star
Sigma Orionis.
The
Horsehead Nebula will slowly shift its
apparent shape over the next few million years and will eventually be
destroyed by
high energy starlight.
