FUSE:
The Far Ultraviolet Spectroscopic Explorer (FUSE) looks at light in the far ultraviolet portion of the electromagnetic spectrum (approximately 90 to 120 nanometers), which is unobservable with other telescopes. FUSE observes these wavelengths with much greater sensitivity and resolving power than previous instruments used to study light in this wavelength range.
