The remote sensing of comets in the ultraviolet bandpass has been a valuabl
e tool for studying the structure, composition, variability, and physical p
rocesses at work in cometary comae. By extension, these studies of comae ha
ve revealed key insights into the composition of cometary nuclei. Here we b
riefly review the ultraviolet studies of comets, and then take a look towar
d the future of such work as anticipated by the advent of several key new i
nstruments.
