International Ultraviolet Explorer (IUE) was an astronomical observatory satellite primarily designed to take ultraviolet spectra. The satellite was a collaborative project between NASA, the UK Science Research Council and the European Space Agency (ESA).

IUE was first proposed in early 1964, by a group of scientists in the United Kingdom, and was launched on January 26, 1978 aboard a NASA Delta rocket. The minimum mission lifetime was initially set for 3 years, but it far exceeded the expectations of the astronomers and engineers and was eventually switched off in 1996, exceeding the planned life by more than a factor of 6. It was the first space observatory to be operated in real time by astronomers who visited the groundstations in the United States and Europe. Astronomers made over 104,000 observations of different objects using IUE, including planets, comets, stars, interstellar gas, supernovae, planetary aurorae, galaxies, and quasars.
