Explanation:
This   
dramatic image peers within M42, the Orion Nebula,   
the closest large star-forming region.   
   
Using data at infrared wavelengths from the   
Herschel   
Space Observatory, the false-color composite   
explores the natal cosmic cloud   
a mere 1,500 light-years distant.   
   
Cold, dense filaments   
of dust that   
would otherwise be dark at visible wavelengths are shown   
in reddish hues.   
   
Light-years long, the filaments weave together   
bright spots that correspond to regions of collapsing   
protostars.   
   
The brightest bluish area near the top of the frame is warmer   
dust heated by the hot Trapezium   
cluster stars that also power the nebula's visible glow.   
   
Herschel data has recently indicated   
ultraviolet starlight from the hot newborn stars   
likely contributes to the creation of   
carbon-hydrogen molecules,   
basic   
building blocks of life.   
   
This Herschel image spans about 3 degrees on the sky.   
   
That's about 80 light-years at the distance of the Orion Nebula.
