Oberon (moon) the spacecraft "Voyager 2" took several images of Oberon in January 1986, allowing 40% of the moon's surface to be mapped. Oberon was discovered by William Herschel on January 11, 1787; on the same day he discovered Uranus's largest moon, Titania. He later reported the discoveries of four more satellites, although they were subsequently revealed as spurious. For nearly fifty years following their discovery, Titania and Oberon would not be observed by any instrument other than William Herschel's, although the moon can be seen from Earth with a present-day high-end amateur telescope. All of the moons of Uranus are named
Oberon (operating system) the "Institut für Systemsoftware" of Johannes Kepler University of Linz, where one of the versions (V4) was maintained, the genealogy of the different versions of the Oberon System was the following: Oberon has a text user interface (TUI), which has to be differentiated from the terminal user interface. It combines the point-and-click convenience of a graphical user interface (GUI) with the linguistic strength of a command line interface (CLI) and is closely tied to the naming conventions of the Oberon language. Any text appearing (almost) anywhere on the screen can be edited and can therefore be used as command input.
