Abstract. Diffuse ultraviolet background radiation may contain important
information concerning the dark matter of the universe. I briefly review
new Voyager observations of the diffuse background, which give a very
low upper limit on the background radiation shortward of Lyman and I
review the capabilities for detection and characterization of diffuse
radiation that will be provided by a proposed new NASA mission. Low-
surface-brightness radiation remains largely an unexplored frontier,
particularly in the ultraviolet.
1. Introduction
While most research in astronomy has focused on study of celestial point sources, the
astronomers of the present IAU Colloquium consider, instead, the low-surface-brightness
universe: extended objects (and backgrounds) that most astronomers have by and large
