Fr.: catalogue de Gliese
A compilation of all known stars within the solar neighborhood with accurately known distances. The first version, Catalogue of Nearby Stars, published in 1957, contained nearly 1000 stars located within 20 pc of Earth, listing their known properties. Gliese published an updated version in 1969, extending the range out to 22 pc. He published the second edition of the catalog in 1979 in collaboration with Hartmut Jahreiss. The combined catalog is now commonly referred to as the Gliese-Jahreiss catalog.

râžmân-e nehešdâd-e jahâni
Fr.: système de positionnement par satellites
A coordinate positioning tool, using a combination of satellites that can rapidly and accurately determine the → latitude, → longitude, and the → altitude of a point on or above the Earth's surface. The GPS is based on a constellation of 24 Earth-orbiting satellites at an altitude of about 26,000 km. The system is a direct application of the thories of → special relativity and → general relativity.

xuše-ye guysân (#)
Fr.: amas globulaire
A spherical aggregate of stars made up of thousands to a few million stars which is an orbiting satellite of a galaxy. There are over 150 globular clusters orbiting our galaxy. Globular clusters are gravitationally → bound systems, highly concentrated to the center (up to a few 103 stars per cubic → light-years), with a volume ranging from a few dozen up to more than 300 light-years in diameter. They are generally old and → metal-poor and are among the first objects to be formed in a galaxy. There is also strong evidence that they form in major galaxy interactions and → mergers. The stars in a globular cluster are thought to have a common origin and thus a single age and → chemical abundance; with some exceptions such as → Omega Centauri and NGC 2808, which exhibit multiple populations. The presence of various sub-populations within a globular cluster is interpreted as indicating distinct epochs of mass → accretion and/or major → star formation. The Milky Way hosts about 200 globular clusters. They are spherically distributed about the → Galactic Center up to a radius of 350 light-years, with a maximum concentration toward the Galactic center. All but the smallest → dwarf galaxies possess globular clusters. Some galaxies, e.g. M87, contain several thousands of them. There are, however, important differences. While all the globular clusters in our Galaxy and in → M31 are old (ages of about 10 billion years, at least), there are galaxies, such as the two → Magellanic Clouds and → M33, that host much younger globular clusters (ages of a few billion years, or less).
Xušé, → cluster; guysân "shaped like a globe," from guy, → globe + -sân "manner, semblance" (variant sun, Mid.Pers. sân "manner, kind," Sogdian šôné "career").
Generally, a small spherical mass, especially a small drop of liquid.
Guycé, fro guy, → globe, + -cé diminutive suffix, from Mid.Pers. -cak, variants -êžak (as in kanicak "little girl," sangcak "small stone," xôkcak "small pig"), also Mod.Pers. -ak.
