FUSE specializes in the ultraviolet wavebands between those of the Hubble Space Telescope and the Extreme Ultraviolet Explorer. It carries high- resolution spectrographs to study emission and absorption lines in stars, galaxies, and the interstellar medium.

Mission Update

Recording the emission and absorption of ultraviolet light with wavelengths from 90 to 120 nanometers, FUSE will fill the gap between the Hubble Space Telescope, which detects only the near ultraviolet, and the Extreme Ultraviolet Explorer.

Space 1998: from the moon to Mars and beyond

Since its launch in June 1992, the Extreme Ultraviolet Explorer satellite has opened a wide window on a largely unexplored slice of the electromagnetic spectrum.

Observing a partly cloudy universe

And we did just that, since we were lucky enough to observe Nova Cygni 1992 with Voyager 2, the Extreme Ultraviolet Explorer (EUVE), and the Rosat X-ray satellite.

Nova Cygni 1992: nova of the century

The ROSAT and Extreme Ultraviolet Explorer satellites have since revealed that Hyakutake is not alone--at least 10 comets, including Hale-Bopp, are now known to exhibit an X-ray glow as they near the sun.
