Abstract. A bright UV GALEX image in the direction of a dense high galactic latitude
interstellar dust cloud is examined to test (and to reject) the idea that a bright extragalactic
UV background radiation field exists. A GALEX "Deep Imaging Survey" image of a second
high latitude region (a region almost totally free of dust) shows a similar bright background,
which, clearly, cannot be due to starlight scattered from interstellar dust. I speculate that the
background is due to dark matter particles interacting with interstellar gas/dust nucleons.
Key words. techniques: ultraviolet cosmology: diffuse background
