The image shows the distribution of cold (blue) and warm (red) dust overlaid on the visible (green, showing distribution of stars) and far-ultraviolet (cyan, indicating the location of young stars) images of M101.


 
The above panels show images of spiral galaxy M101 overlaid with information from FIS.

The left panel shows the distribution of the cold dust in the galaxy. Whereas the right panel shows the distribution of warm dust in the spiral galaxy.


 
The image shows the distant Universe seen at far-infrared wavelengths (90 micrometres) through the Galactic window near the South Ecliptic Pole in the sky. Many faint galaxies are seen in white over the wide area of 10 square degrees. Observation fields of other deep surveys at other wavelengths are overlaid.


 
The images show the distant Universe seen at four different far-infrared wavelengths through the Galactic window near the South Ecliptic Pole in the sky.Many faint galaxies are seen in white over the wide area of 10 square degrees. Observation fields of other deep surveys at other wavelengths are overlaid.

Differences in the brightness of individual galaxies in the different wavelength bands are seen.
