description EXOSAT Overview
EXOSAT was a European Space Agency space observatory launched in 1983 to study X-ray sources beyond Earth. Operating until 1986, it observed objects within and outside the Milky Way, including compact stars, binary systems, active galactic nuclei, and other variable high-energy sources. Its highly eccentric orbit permitted unusually long, uninterrupted observations, making the mission particularly useful for examining how the X-ray brightness of astronomical objects changed over time.
