An infrared image of M16, the Eagle Nebula, taken by the ESA/ISO satellite. The false-color image was constructed from a 7.7 micron infrared exposure (shown as blue), and a 14.5 micron infrared exposure (shown as red). This nebula is the site of active star formation in the Milky Way Galaxy. WISE will observe the region in similar wavelengths of light to see the dust that often enshrouds star forming regions.
