A star catalogue is an astronomical catalogue that lists stars. In astronomy, many stars are referred to simply by catalogue numbers. There are a great many different star catalogues which have been produced for different purposes over the years, and this article covers only some of the more frequently quoted ones. Star catalogues were compiled by many different ancient people, including the Babylonians, Greeks, Chinese, Persians, and Arabs. They were sometimes accompanied by a star chart for illustration. Most modern catalogues are available in electronic format and can be freely downloaded from space agencies' data centres. The largest is being compiled from the spacecraft Gaia and thus far has over a billion stars.

The Omo River in southern Ethiopia is the largest Ethiopian river outside the Nile Basin. Its course is entirely contained within the boundaries of Ethiopia, and it empties into Lake Turkana on the border with Kenya. The river is the principal stream of an endorheic drainage basin, the Turkana Basin.

<span class="mw-page-title-main">Omo Kibish Formation</span> Geological formation in the Low Omo Valley of southwestern Ethiopia

The Omo Kibish Formation or simply Kibish Formation is a geological formation in the Lower Omo Valley of southwestern Ethiopia. It is named after the nearby Omo River and is subdivided into four members known as Members I-IV. The members are numbered in the order in which they were deposited and date between 196 ka ~ 13-4 ka. Omo Kibish and the neighboring formations have produced a rich paleoanthropological record with many hominin and stone tool finds. The Kibish formation, in particular, is most notable for Richard Leakey's work there in 1967 during which he and his team found one of the oldest remains of anatomically modern Homo sapiens. Known as Omo Kibish 1, the fossil was dated to 196 ± 5 ka old and is among two other Omo remains that were found in Member I. The Omo fossils were more recently re-dated to approximately 233,000 ka old. In the early 2000s a research boom enriched the knowledge base about the Kibish Formation. Study of the faunal remains and stone tools provided insight into the archeological associations of Homo sapiens and thereby their behaviors and the complex environmental contexts in which they lived and evolved.

Selamago is a woreda in the Southern Nations, Nationalities, and Peoples' Region of Ethiopia. Part of the Debub Omo Zone, Selamago is bordered on the south by Nyangatom, on the west and north by the Omo River which separates it from the Bench Maji, Keffa and Konta, on the northeast by the Gamo Gofa, on the east by the Basketo and Bako Gazer, and on the southeast by the Usno River which separates it from Bena Tsemay; the Mago River defines part of the boundary with Bako Gazer.

The Shungura Formation is a stratigraphic formation located in the Omo river basin in Ethiopia. It dates to the Late Pliocene to Early Pleistocene.

LSR J1835+3259 is a nearby ultracool dwarf of spectral class M8.5, located in constellation Lyra, the discovery of which was published in 2003. Previously it was concluded that this star is a young brown dwarf, but no lithium absorption lines are detected for this object, which is a strong indicator for young brown dwarfs that need 10-100 million years to deplete lithium.
