All-Wavelengths Galactic Center Photo

It seems that beautiful pics of galactic structures are a dime a dozen.  But this one just caught my eye.  

This is what the Wired Blog said about the pic:
  • In celebration of the International Year of Astronomy 2009, NASA's Great Observatories -- the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory -- have collaborated to produce an unprecedented image of the central region of our Milky Way galaxy 
  • Each telescope's contribution is presented in a different color: Yellow represents the near-infrared observations of Hubble. They outline the energetic regions where stars are being born as well as reveal hundreds of thousands of stars. Red represents the infrared observations of Spitzer. The radiation and winds from stars create glowing dust clouds that exhibit complex structures from compact, spherical globules to long, stringy filaments. Blue and violet represents the X-ray observations of Chandra. X-rays are emitted by gas heated to millions of degrees by stellar explosions and by outflows from the supermassive black hole in the galaxy's center
  • It truly is a fascinating image.  What is even more amazing is the fact that the composite photo covers.  This whole photo covers just 1/2 of a degree, about the width of the full moon.
