IUE Fact Sheet

IUE, or International Ultraviolet Explorer, was a ESA/NASA-UK venture. It analysed ultraviolet light from the stars, which is blocked by the Earth's ozone layer but often carries storm signals of cosmic upheavals. Launched in 1978, IUE operated until 1996, making it one of the longest-lived astronomical satellites.
