Galactic Cirrus

This image shows the dramatically different view of our sky when viewed in far infrared light. At this wavelength of 100 microns, the light from stars is imperceptible against the cool glow of vast dust clouds warmed by the stars' light. In visible light such dust blocks our view of more distant stars and galaxies, but in far-infrared light it glows dramatically. Significantly, some of it also reflects blue light that can be captured in very deep optical exposures.

Image was made from data from IRAS and COBE.
