Observing the Universe

Observando el Universo

Four board compositions of two overlaid images of the same celestial object. The upper image corresponds to images of the objects observed in optical wavelengths, while the lower image corresponds to X-ray observations. To see the Universe either in one frequency or the other, the upper image has flaps that, once lifted, allow the view of the lower image. We recommend printing this material on a foam core board in A3 format.
